4 to fill the 2p shell
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
Vanadium has on the outer shell two electrons.
Helium (He) has 2 electrons in its outer shell. Calcium (Ca) has 2 electrons in its inner shell and 8 electrons in its outer shell.
outer shell electrons are knows as Valence Electrons
2 outer shell electrons
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
There is a total of 8 electrons that are needed to fill outer shell of most atoms. An atom is the smallest unit of matter.

No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Calcium has two electrons in the outer shell.
Bromine has 7 electrons in its outer shell.
Vanadium has on the outer shell two electrons.
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
