Answer 2

The symbols for the following elements are:

1. Calcium - Ca

2. Sodium - Na

3. Magnesium - Mg

4. Argon - Ar

Explanation:

A chemical symbol is a way of portraying an element in a quick and easy way. Instead of writing down the name of an element, we use one or two letters to symbolise it. Chemical equations are easier to write with symbols. Symbols are also universally recognised.

For example:

Hydrogen + Oxygen = Water ; does not give the whole information regarding the equation, instead $2H_{2} + O_{2} = 2H_{2}O$; gives the information of how many moles of reactants is used and the number of moles produced.
