- Isotopes of an element have the same number of protons and elections but a different number of neutrons. This means there is no difference in the way that they react with oth … er elements or compounds as the electron configuration has not changed. The only difference is their new atomic mass. eg.he sum of the protons and neutr … ons is the mass number. For example, helium exists as 3He(2 protons and one neutron) or as 4He (2 protons and 2 neutrons). The two forms of helium are called isotopes of helium. Isotopes of an element have the same chemical properties but different weights.

How do isotopes and atoms differ? What if there are more neutrons than the generalized ones? They are called isotopes. For example, a hydrogen atom has one proton and one electron (no neutrons). One isotope of hydrogen called deutorium has one proton , one electron and one neutron. Another isotope of hydrogen called tritium has one proton, two neutrons and one electron. Tritium is radioactive.

- 1 Note that the relative atomic masses listed on the periodic table are average values for the associated element. 2  Chemical elements have different isotopes-chemical forms that differ in mass because of the addition or subtraction of one or more neutrons to the atom's nucleus.

What is an Isotope ? Definitions of an isotope: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Another way to say the same thing is: Isotopes are atoms of the same element that have the same atomic number (whose symbol is Z) but different mass numbers (whose symbol is A).

What Are Isotopes? - Definition, Types & Examples Not all atoms of an element are identical - atoms of the same element can have different number of neutrons. These different versions of the same element are called isotopes. In this lesson, we will discuss the examples and types of isotopes. MCAT Test: Practice and Study Guide / Standardized Tests Courses.

Isotope Different isotopes behave basically the same way chemically, because chemistry is determined by the electric charge. There are some slight changes in the chemistry of different isotopes of hydrogen, these isotopes are called protonium (no neutrons, the most common form), deuterium (one neutron) and tritium (two neutrons).

- This difference in the number of neutrons imparts different physical properties to the isotopes. Many of the elements found in nature comprise a mixture of different isotopes.The most stable isotopes of elements are those with roughly equal amounts of protons and neutrons.

Atom Isotopes are atoms of the same element that have the same number of protons, but different numbers of neutrons, and therefore different masses. Unstable isotopes are radioacti…ve and undergo radioactive decay of their nuclei, while stable isotopes do not undergo radioactive decay.

What Are Some Ways That the Isotopes of an Element Differ From Each Other? The isotopes of an element differ from each other in their mass numbers and the number of neutrons they contain. All of the isotopes of an element, however, contain the same number of protons, which is equal to that element's atomic number.

Isotopes and Atomic Mass 1 Predict how the mass and name of an isotope will change given a change in the number of protons, neutrons or electrons. 2  Predict how the average atomic mass of an element changes given a change in the abundance of its isotopes.

- Atoms with same Z number but different mass numbers are called isotopes. ( Isotopes means same place, all these are put in the same place in the periodic table). Most of the elements have isotopes, some 1 or 2 or a few, other several. Element tin has 10 isotopes. Some isotopes are stable, whereas others are not stable? Why?

- 1 The elements, if arranged according to their atomic weights, exhibit an evident stepwise variation [12] of properties. 2  Chemically analogous elements have either similar atomic weights [13] (Pt, Ir, Os), or weights which increase by equal increments (K, Rb, Cs).

What is an Isotope ? 1 The mass number (A) of an atom is the sum of the protons and neutrons in the atom: mass number A = (number of protons) + (number of neutrons). 2  Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons in their atomic nuclei. The mass number (A) of an atom is the sum of the protons and neutrons in the atom: mass number A = (number of protons) + (number of neutrons). 2  Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons in their atomic nuclei.

Atoms, Molecules, and Ions Terms Atomic number, atomic mass, and isotopes. Fundamental properties of atoms including atomic number and atomic mass. The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.

In simple words, what are Isotopes? Simply put, isotopes are atoms with the same number of protons but different numbers of neutrons. Uranium 235 and Uranium 238 are isotopes of uranium. Because only the number of neutrons is involved, all isotopes are chemical elements, not molecules or compounds.

Isotope analysis Isotope analysis can be used by forensic investigators to determine whether two or more samples of explosives are of a common origin. Most high explosives contain carbon, hydrogen, nitrogen and oxygen atoms and thus comparing their relative abundances of isotopes can reveal the existence of a common origin. Researchers have also shown that analysis of the 12 C/ 13 C ratios can locate the country of origin for a given explosive.

Isotope analysis For example most carbon is present as 12 C, with approximately 1% being 13 C. The ratio of the two isotopes may be altered by biological and geophysical processes, and these differences can be utilized in a number of ways by ecologists.

Isotope Separation Isotope separation. The physical separation of different isotopes of an element from one another. The different isotopes of an element as it occurs in nature may have similar chemical properties but completely different nuclear reaction properties. Therefore, nuclear physics and nuclear energy applications often require that the different isotopes be separated.

What are the differences between ions and isotopes? The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.

- Isoelectronic Configurations. We already know that elements with similar electronic configurations tend to have similar chemical and physical properties. It is possible, in fact common, for elemental ions to have not only similar but exactly the same electronic configurations as other elements or ions.

Chapter Two Review Isotopes have the same number of protons, but differ in the number of neutrons they carry. The majority of elements have two or more structural variations called isotopes. Isotopes of an element have the same number of protons, but differ in the number of neutrons they contain. Isotopes are not necessarily present in equal amounts in a given element.

What is the difference between an element and a isotope? Due to a difference in number of neutrons, they also have different masses. For example, take the element carbon. Carbon could have s … ix neutrons (12C) or eight neutrons (14C). Both 14C and 12C are isotopes of carbon and therefore have different masses.ll isotopes for the same element have the same number of protons, but a different number of neutrons. This means isotopes have different properties, such as different weights-but are all still the same element.

Neutron The atomic number defines the chemical properties of the atom, and the neutron number determines the isotope or nuclide. The terms isotope and nuclide are often used synonymously, but they refer to chemical and nuclear properties, respectively. The atomic mass number, symbol A, equals Z+N.his radioactive decay, known as beta decay, is possible since the mass of the neutron is slightly greater than the proton. The free proton is stable. Neutrons or protons bound in a nucleus can be stable or unstable, however, depending on the nuclide.

Chapter 3 Molecules and Atoms Chapter Review Chapter 3 Molecules and Atoms Chapter Review. 1. Define isotope. A. each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
