Question

How many electrons will the element gain or lose in order to obtain a noble gas structure?

Answer 1

It depends on the element.

Answer 2

Elements in group 1

Answer 3

Elements in Group 1 are alkali metals. They all have 1 electron in their valence subshell. So, they tend to lose their electron. When they lose an electron, they have as many electrons as the closest noble gas, which should be 1 atomic number down.
