Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
An unstable isotope can disintegrate.
A radio-isotope.
When an isotope is unstable, it is said to be radioactive.
false
A stable isotope does not decay and therefore, maintains a constant concentration on Earth. An unstable isotope, also known as a radioactive isotope, decays at a predictable and measurable rate on Earth. An unstable isotope may decay by the ejection of an electron or positron, known as beta decay, or by the ejection of two protons and two neutrons, known as alpha decay.
Isotopes are atoms of a particular element with different numbers of neutrons. A radio isotope is an isotope that is radioactive because the nucleus is unstable.

isotope
Each (unstable) isotope has a distinctive half-life.
Isotopes are atoms of a particular element with different numbers of neutrons. A radio isotope is an isotope that is radioactive because the nucleus is unstable.
No, it is a natural stable isotope.
Hydrogen has 1 unstable isotope, and 2 stable isotopes.
its nucleus is unstable
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
It isn't really an ELEMENT that is unstable, but an ISOTOPE. That means that in general, for the same element, some atoms will decay, and some will not - the difference being the number of neutrons in the nucleus.
