Electron configuration was used to group element with the same valance electron together. They also tend to have similar properties.

Explanation:

For simple explanation I will talk about only a representative element such as :
11Na : 1s^2 2s^2 2p^6 3s^1
19K : 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1

you can see that Na and K was in the same group because their valance electron were in s orbital and only has 1 electron.
So if you do electron configuration with column 2 of periodic table you will also get 2 valance eleectrons in s orbital for Mg and Ca etc.
