3. the total number of protons and neutrons in a nucleus.
6. the process or result of joining two or more things together to form a single entity.
7. the time taken for the radioactivity of a specified isotope to fall to half its original value.
9. he third letter of the Greek alphabet ( Γ, γ ), transliterated as ‘g.’.
10. a radioactive isotope.
12. each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
13. the action of dividing or splitting something into two or more parts.

2. the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
4. the second letter of the Greek alphabet ( Β, β ), transliterated as ‘b.’.
5. a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
8. the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei.
11. a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
