Succesive radioactive disintegrations in a radioactive series.
false
1. All the radioactive isotopes are unstable ! 2. Yes, it is true, the parent isotope (radioactive and unstable) decay and form daughter products.
Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Technically the answer is false, however the answer most tests accept as the correct answer is True.According to Nuclear theory when a parent undergoes decay and produces a daughter isotope the daughter may be stable or it may be unstable and further decay until a final stable granddaughter isotope is formed. This process is called a decay chain, however since eventually a stable isotope is formed the acceptable answer is True, even though technically it is not the case.
A radio-isotope.

Daughter Elements
A radio-isotope.
When an isotope is unstable, it is said to be radioactive.
... an unstable isotope to a more stable isotope by emission of some type of radiation (alpha, beta, or gamma).
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.
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.
