2 answers:
Answer: 1: 1
Explanation:
An ionic bond is formed when an element completely transfers its valence electron to another element. This bond is formed between a metal and a non-metal.
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here potassium forms a cation ion by loss of one electron and bromine forms an anion
by gain of one electron.Thus one
combine with one
to form neutral
