To find the charge of a non-metal element we take 8 and subtract the group the element is in. Example 8 - 6 =

I am still confused about what is the difference of -ide and -ate.

Is the charges of majority of elements can be known as the group no.

When writing chemical formulas, we find the symbol of the elements and the charge. The charges must be criss-crossed and must be written below the symbol of the element on the bottom right. This signifies the number of elements. When the number is the same, it can be removed.

I am still confused on writing the formula for the chemical bonding

Why do the atoms readily discard electrons so that their electronic configuration resembles a noble gas configuration ? What makes noble gases so special that other atoms want to be like them ?

# data[].attributes.body
To find the charge of a metal element, look at the group number and you will find the charge.

When drawing the electronic configuration for ionic bonds , make sure that the charge is able to have forces of attraction
