If an atom of bromine (br) becomes an ion, which of the following does it most likely form?
a. br+
b. br7+
c. br-
d. br7-

An atom of Bromine (Br) forms an ion and becomes Br⁻

Explanation:

Atoms of elements gain or lose electron(s) to attain a stable configuration and form ions. When an atom gains electron(s) it forms a negatively charged ion called an anion. For example, Bromine is a halogen and its atom requires to gain one electron to attain stability and form a bromine ion (Br⁻).When an atom loses electron(s) it forms a positively charged ion called a cation. For instance, atoms of calcium(Ca) requires to lose two electrons to attain stability and form calcium ion (Ca²⁺).

The density would be 1.622
