- The reason radioactive isotopes emit radiation is that the emission of radiation is a nutural consequence of being radioactive.Let's look a bit more closely. Radioactive isotopes are unstable atoms, and they will undergo radioactive decay sooner or later.The unstable atomic nuclei undergo a change based on what particular isotope is being considered. In any case, when a nuclear change occurs, radiation of some kind is emitted from that nucleus. 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 st … able. This is called Carbon12.

- Answer by Umbr3on. Confidence votes 487. an isotope is an atom that is heavier or lighter than a normal atom of the same element. the number of protons is different. for example, carbon usually has an atomic mass of 12: 6 protons, 6 neutrons. but in carbon 14 (an isotope of carbon), there are 6 protons and 8 neutrons.

How do isotopes of the same element differ from each other? How do the atoms of one isotope differ from those of other isotopes of the same element? Primarily, isotopes differ in the number of neutrons in the nucleus. Secondarily, because some combinations of protons and neutrons produce an unstable nucleus, they may diffe … r by being radioactive.

Genome Glossary Isotopes are different types of atoms of the same element. These isotope will have the same atomic number (protons), but will differ in number of neutrons. An example of an is … otope: carbon, carbon12 is the elemental form, carbon14 is an isotope of Carbon.aid another way, one element may exist in a number of different forms called isotopes. Each element has a number of different isotopes, and this is determined by the number of neutrons in the nucleus. Let's look at an example.

Biology, Eighth Edition (Raven) Radioactive isotopes are versions of elements such as carbon, nitrogen, or phosphorus that unstable and release neutrons to become more stable isotopes. The radioactive signal given off by the emission of neutrons allows scientists to detect the isotopes even when they cannot be seen. Adding isotopes to biological systems allows scientists to trace both molecular pathways and the locations at which these pathways occur.

What Are Some Ways That the Isotopes of an Element Differ From Each Other? These three carbon isotopes are called carbon-12, carbon-13 and carbon-14, respectively. The atomic mass of each of these isotopes is derived by adding the number of neutrons in each isotope to the number of protons. The atomic mass of carbon-14, for example, is 14, because 6 protons plus 8 neutrons equals an atomic mass of 14.

Isotope Thus different isotopes of a given element all have the same number of electrons and share a similar electronic structure. Because the chemical behavior of an atom is largely determined by its electronic structure, different isotopes exhibit nearly identical chemical behavior. 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.

What is an Isotope? An isotope is a variant on an element that has a different atomic weight from other variants. Except for the commonest form of hydrogen — which has only a proton — every atomic nucleus in normal matter is made of both protons and neutrons.oo many neutrons can also make an isotope unstable. For example, the commonest form of hydrogen has one proton and no neutrons, but there are two other forms, with one and two neutrons, called deuterium and tritium, respectively.

What makes some isotopes have an unstable nuclei and others not? They are unstable because they can not hold together, they have too many or too few neutrons. The are called radio-isotopes. The disintegrate by emitting a particle or an atom into another element. The new element may be a radio-isotope too. I hope it's clear!!!

- 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?

Isotopes An isotope is one of two or more species of atoms of a chemical element with the same atomic number (same number or protons in the nucleus) and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.

Why are Isotopes Important ? There are 90 naturally occurring elements with roughly 250 stable isotopes, and over 3200 unstable or radioactive isotopes. Different isotopes of the same element often have completely different properties -- making some of them invaluable for mankind, and others worthless [for the time being].

Isotope Stability Chemistry Tutorial 1 A stable isotope is one that does not emit radiation, or, if it does its half-life is too long to have been measured. 2  It is believed that the stability of the nucleus of an isotope is determined by the ratio of neutrons to protons. 3  Observations of the atomic number of isotopes show us that:

- 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.

isotope For any element, one of the isotopes is more abundant in nature than any of the others, although often multiple isotopes of a single element are mixed. The isotope of an element is defined by the nucleon number, which is the sum of the number of protons and the number of neutrons in the atomic nucleus.

Radioactive tracer Isotopes of a chemical element differ only in the mass number. For example, the isotopes of hydrogen can be written as 1H, 2H and 3H, with the mass number at top left. When the atomic nucleus of an isotope is unstable, compounds containing this isotope are radioactive. Tritium is an example of a radioactive isotope.

- Jupiterimages/Creatas/Getty Images. Radioactive isotopes, also called radioisotopes, are atoms with a different number of neutrons than is usual, making them unstable. A radioisotope's nucleus decays, emitting alpha, beta and gamma rays until the isotope reaches stability.Once it’s stable, the isotope may become another element entirely, such as when uranium decays into lead.ignificance. Radioactive isotopes are useful because they produce alpha, beta and gamma rays. The radiation’s penetrating power depends on its energy, particle mass, and the object’s density. These properties lead to many practical applications in science, medicine and industry.

What are radioactive isotopes? When an unstable nucleus of a radioactive isotope spontaneously  decays, the radioactive decay process is normally gamma radiation,  beta particle or alpha particle emission … .his is called Carbon12.   Carbon14 with 6 protons and 8 neutrons, is unstable and decays by releasing a beta particle from its nucleus to become a stable isotope, Nitrogen14. which has 7 protons and 7 neutrons. That refers to an isotope that is unstable-the atoms will decay after a while.
