✓
Answer
SOLUTION 1. In naming a compound containing a metal and a non-metal, the name of the metal is written first and the name of the non-metal is written next after adding the suffix-ide to its name.
Examples:
NaCl - Sodium chloride
AgBr - Silver bromide
2. In naming a compound containing a metal, a non-metal and oxygen, name of the metal is written first and name of the non-metal with oxygen is written next after adding the suffix- ate (for more atoms of oxygen) or -ite (for less atoms of oxygen) to its name.
Examples:
$Na _2 SO _4$ - Sodium sulphate
$Na _2$-Sodium nitrite
3. In naming a compound containing two non - metals only, the prefix mono, di, tri, tetra, penta etc. is written before the name of non - metals.
