Answer 1

The cation is written before the anion in the name and formula of an ionic compound.

Answer: Option B

Explanation:

An ionic compounds are a chemical compound at which ions usually held together by an ionic bonds. Typically, a positively charged residue consists of metal cations, while a negatively charged residue consists of an anion or a poly-atomic ion. The ionic compound is mentioned first by a cation after with an anion. The cations have the same name as its element.

For example, $K^{+1}$  is called the potassium ion but simply 'K' refers potassium atom. Anion is called by the name of the element, removing the end part and adding "ide". For example, $F^{-1}$  is called fluorine, an element called fluorine. 'ine' was replaced with an 'ide'. To name the compound, the cation and anion names are added together. For example, NaF (sodium fluoride).
