List of elements by stability of isotopes For each of the 80 stable elements, the number of the stable isotopes is given. Only 90 isotopes are expected to be perfectly stable, and an additional 163 are energetically unstable, but have never been observed to decay. Thus, 253 isotopes (nuclides) are stable by definition (including tantalum-180m, for which no decay has yet been observed).

- 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 of astatine Lighter astatine isotopes have quite high energies of alpha decay, which become lower as the nuclei become heavier. However, astatine-211 has a significantly higher energy than the previous isotope; it has a nucleus with 126 neutrons, and 126 is a magic number (corresponding to a filled neutron shell).

Radium All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1600 years and decays into radon gas.When radium decays, ionizing radiation is a product, which can excite fluorescent chemicals and cause radioluminescence.26 Ra is the most stable isotope of radium and is the last isotope in the (4 n + 2) decay chain of uranium-238 with a half-life of over a century. Its immediate decay product is the dense radioactive noble gas radon, which is responsible for much of the danger of environmental radium.

- Elements with atomic numbers of 83 and less, have isotopes (stable nucleus) and most have at least one radioisotope (unstable nucleus). As a radioisotope tries to stabilize, it may transform into a new element in a process called transmutation. We will talk about transmutation in more detail a little later. Review: 1  Radioactivity is the release of energy and matter due to a change in the nucleus of an atom.

Isotopes of carbon There are three naturally occurring isotopes of carbon: 12, 13, and 14. 12 C and 13 C are stable, occurring in a natural proportion of approximately 99:1. 14 C is produced by thermal neutrons from cosmic radiation in the upper atmosphere, and is transported down to earth to be absorbed by living biological material.arbon-15 redirects here. For the firearm, see Carbon 15. Carbon (C) has 15 known isotopes, from 8 C to 22 C, 2 of which (12C and 13C) are stable. The longest-lived radioisotope is 14C, with a half-life of 5,700 years.

- Astatine is a very rare radioactive chemical element with the chemical symbol At and atomic number 85. It occurs on Earth as the decay product of various heavier elements. All its isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours. Elemental astatine has never been viewed because any macroscopic sample would be immediately vaporized by its radioactive heating. It has yet to be determined if this obstacle could be overcome with sufficient cooling.

The half-life of one of the radioisotopes of chromium is extremely long – the most stable one, 50Cr, has a half-life of over 1.8×1017 years. On the other hand, the radioisotope 51Cr has a half-life of less than 28 days. The rest of the radioactive isotopes have even shorter half-lives - under 24 hours.

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.

Isotopes of tungsten On average, two alpha decays of 180 W occur per gram of natural tungsten per year so for most practical purposes tungsten can be considered stable. Theoretically, all five can decay into isotopes of element 72 (hafnium) by alpha emission, but only 180 W has been observed to do so.

Tin In contrast, α-tin (nonmetallic form, or gray tin), which is stable below 13.2 °C (55.8 °F), is brittle. α-tin has a diamond cubic crystal structure, similar to diamond, silicon or germanium. α-tin has no metallic properties at all because its atoms form a covalent structure in which electrons cannot move freely.

Hydrogen Hydrogen has three naturally occurring isotopes: H (protium), H (deuterium), and H (tritium). Other highly unstable nuclei (H to H) have been synthesized in the laboratory, but do not occur in nature. The most stable radioisotope of hydrogen is tritium, with a half-life of 12.32 years. All heavier isotopes are synthetic and have a half-life less than a zeptosecond (10sec). Of these, H is the most stable, and the least stable isotope is H .

- Chemical elements contains 11 transuranic actinide elements, with atomic numbers ranging from 93 to 103. An element is defined by its atomic number, the number of protons in the atomic nucleus. Nuclei with the same atomic number but different numbers of neutrons are isotopes of the same element.H TRU has a surface dose rate not greater than 2 mSv per hour (200 mrem /h), whereas RH TRU has rates of 2 mSv/h or higher. CH TRU has neither the high radioactivity of high level waste, nor its high heat generation.

- Number of neutrons. However, not all nitrogen nuclei have 8 neutrons in a nucleus. They can have 5, 6, 7, 8, 9, 10 or 11 neutrons. We call these different isotopes of nitrogen. There are always 7 protons because the nucleus is always a nitrogen nucleus (Z=7).Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers. The isotopes of nitrogen have mass numbers ranging from 12 to 18.We call them nitrogen-12, nitrogen-13, nitrogen-14 and so on. Some isotopes of nitrogen are unstable.here are always 7 protons because the nucleus is always a nitrogen nucleus (Z=7). Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers.
