covalent bond
Yes, nonmetals generally gain electrons to fill valence shells.
Electron shells
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
All these have one electron in their valence shell.

Covalent bond
Yes they have eight electrons in their valence shells. This is why they are not reactive. All elements have valence shells.
The value of 'n' for the valence shells is the number of shells that specific atom has
Radium has seven electron shells; the valence of radium is 2+.
Yes, nonmetals generally gain electrons to fill valence shells.

No, carbon has 4 valence electrons.
Period number = no. of electron shells. Therefore neon has two shells.
Beryllium has one valence shell containing two electrons.
