Question

when a neutral atom gains one or more electrons from its valence shell ________ is formed. an isotope an anion a photon a cation question 4 1 pts ionic compounds are composed of ions and are called ________. molecules heterogeneous isomorphic salts

Explanation:

1. When a neutral atom gains one or more electrons, it becomes negatively - charged. This negatively - charged particle is called an anion. An isotope is an atom with the same number of protons but different number of neutrons. A photon is a quantum of electromagnetic radiation. A cation is a positively - charged particle formed when an atom loses electrons.
2. Ionic compounds are composed of ions and are called salts. Molecules are formed by the sharing of electrons in covalent bonds. Heterogeneous refers to a non - uniform mixture. Isomorphic refers to having the same form or structure.

Answer:

1. B. an anion
2. D. salts
