What are the properties of radioactive decay?
Radioactive decay has the following properties: 1. No element can completely decay. 2. The number of atoms decaying in a particular period is proportional to the number of atoms present in the beginning of that period. 3. Estimate of radioactive decay can be made by half life and decay constant of a radioactive element.

Can the atomic number change over time?
No. The atomic number of an element never changes. It is the number of protons and it defines the element. In certain types of radioactive decay, the number of protons can change, but then it is no longer the same (parent) element, but rather is a new (daughter) element.
What is first radioactive element of periodic table?
Bismuth
How many protons are needed for a element to be naturally radioactive?
Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.
