As a radioactive element emits gamma radiation only, the atomic number of the element increases or decreases

Ionic compounds can be made from a metallic ion and a nonmetallic ion. Metallic ions (M) are positive (cations). Nonmetallic ions (N) are negative (anions). x stands for the number of metallic ions and y stands for the number of nonmetallic ions.
