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).

Chemical element Isotopes are atoms of the same element (that is, with the same number of protons in their atomic nucleus), but having different numbers of neutrons. Most (66 of 94) naturally occurring elements have more than one stable isotope.Thus, for example, there are three main isotopes of carbon.he mass number of an element, A, is the number of nucleons (protons and neutrons) in the atomic nucleus. Different isotopes of a given element are distinguished by their mass numbers, which are conventionally written as a superscript on the left hand side of the atomic symbol (e.g., 238 U).

- 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?

- We'll learn about what isotopes are and how to write atomic number and mass number in isotope notation. We talk about a simple analogy with cars to explain this tutorial. Isotopes are versions of an atom or an element that have the same number of protons, but different numbers of neutrons.

Definition of Element Although an element's atoms must all have the same number of protons, they can have different numbers of neutrons and hence different masses. When atoms of the same element have different numbers of neutrons, they are called isotopes.

What are radioactive isotopes? Making the world better, one answer at a time. A radioactive isotope is a form of an element that is unstable and eventually decays into a different element. For example, most Carbon has 6 protons and 6 neutrons, and is stable.aking the world better, one answer at a time.

Isotopes The word isotopes originates from the Greek language and means equal places. Molecules of different masses of the same element were called isotopes a term first used by Frederick Soddy in 1913. The name isotope comes from Greek isos meaning equal and topos meaning place and reflects the fact that isotopes are at the same place on the periodic table. Today more than 2200 isotopes of the 92 naturally occurring elements are known.

- An isotope has same number of protons but a different number of neutrons as the original element in the atomic nucleus; it has the same atomic number as the element which isn' … t an isotope, but will have a different mass number.

- A nuclide, also known as an isotope, … is a nucleus with a specified number of both protons and neutrons. So, for example, we know that the element carbon always has six protons in its nucleus; that is what makes it carbon rather than a different element. But it can have different numbers of neutrons.ll of the different nuclei that exist that have the same number of protons, but different number of neutrons, are isotopes of whatever atom is being defined by the number of protons in that nucleus.

Chemical Principles/Atoms, Molecules, and Ions Atoms with the SAME number of protons/electrons but DIFFERENT numbers of neutrons are called isotopes. Now ALL chemical properties of an atom are determined by the number of electrons in it ONLY (which by definition is equal to the number of protons in the nucleus).

What are Isotopes? To see all my Chemistry videos, check out. http://socratic.org/chemistry. We'll learn about what isotopes are and how to write atomic number and mass number in isotope notation. We talk about a simple analogy with cars to explain this tutorial. Isotopes are versions of an atom or an element that have the same number of protons, but different numbers of neutrons. Isotopes and isotope notation are particularly important in nuclear chemistry.

Isotope 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. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively. Isotope analysis is the determination of isotopic signature, the relative abundances of isotopes of a given element in a particular sample. 2  For biogenic substances in particular, significant variations of isotopes of C, N and O can occur.

Isotopes Definition and Examples in Chemistry Isotope Examples. Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth's crust.

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 Isotopes are variants of a particular chemical element which differ in neutron number, although all isotopes of a given element have the same number of protons in each atom.or example, 14C is a radioactive form of carbon while 12C and 13C are stable isotopes. There are about 339 naturally occurring nuclides on Earth, of which 288 are primordial nuclides, meaning that they have existed since the solar system's formation.

Atom Definition 1: Isotopes of an element have the same number of protons (same Z), but a different number of neutrons (different N). The chemical properties of the different isotopes of an element are the same, but they might vary in how stable their nucleus is.

How do isotopes and atoms differ? Isotopes are atoms of same kind (protons/electrons) but different number of neutrons, then different mass, they might be natural or manmade (deuterium and tritium are examples for both conditions for hydrogen), when they are natural the periodic chart shows a rational mass number where the fractional part gives a proportion of natural occurrence of ...

CONTENTS ￮ Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. ￮ Changing the numbers of protons, electrons, or neutrons changes an atom and can create different elements. and isotopes; isotopes are atoms of a single element that differ in number of neutrons, and can be stable or. unstable. ￮ Elements each have different properties that are useful to people in different ways.

Isotopes Isotopes vs. Nuclides. A nuclide is any particular atomic nucleus with a specific atomic number Z (the number of protons) and mass number A (the number of protons plus the number of neutrons). Collectively, all the isotopes of all the elements form the set of nuclides. There are more than 3,100 nuclides identified in the Chart of Nuclides.

Isotope From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons. Isotopes are variants of a particular chemical element which differ in neutron number. All isotopes of a given element have the same number of protons in each atom.

Registered Nurse (RN) A registered nurse (RN) is one of many different types of nurses. A registered nurse is a nurse who has completed at least an associate’s degree in nursing (ADN) or a bachelor of science degree in nursing (BSN) and has successfully passed the NCLEX-RN certification exam.

- Isotopes: When Atomic Weights Vary a. Isotopes are atoms with same number of protons and electrons but differing in number of neutrons and therefore weight; for example: 14C is an isotope of 12C. b. Radioactive isotopes are unstable; as they decay, they emit radiation detected by a special counter or scanner.

What are the differences between ions and isotopes? 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. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively.
