Question

If an atom of Bromine (Br) becomes an ion, which of the following does it most likely form?

Answer 1

Answer:

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⁺).
