covalent bond
A covalent bond occurs when the strength of the valence shells of atoms is similar. In a covalent bond, atoms share electrons to achieve a stable electron configuration.

All these have one electron in their valence shell.
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
It needs only 1 more electron since it already has 7 valence electrons.

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+.

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.
They have filled valence shells. Atoms undergo chemical bonding in order to have filled valence shells by sharing electrons or transferring electrons. Because the noble gases already have filled valence shells, they have no need to react with other elements.
All these have one electron in their valence shell.
