Write an equation that shows the formation of a sodium ion from a neutral sodium atom.

The answer to your question is given below.

Explanation:

Sodium (Na) is a group 1 element because it has 1 electron in it's outermost shell.

Sodium ion (Na+) is formed when sodium atom (Na) lose it's outermost electron to attain the octet configuration of the noble gas element.

This can further be seen from the equation given below:

Na —> Na+ + e

Thus, we can represent the above in electronic configuration form as follow:

Na (11) => 1s² 2s²2p⁶ 3s¹

Na+ (10) => 1s² 2s²2p⁶

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
