As long as the valence shell is filled, it can be any number.
When the atom has 8 valence electrons.
The nucleus of an atom in a covalent bond wants to attract and share electrons with other atoms to achieve a stable electron configuration. This sharing of electrons allows atoms to fill their outer electron shells and become more stable.
In a coordinate ionic bond, one atom donates both electrons to the other atom, creating a stable compound.

ionic bonds form when one atom gains electrons or loses electrons to another atom covalent bonds form when one 2 atoms share electrons in both types of bonding atoms bond to become more stable (to become similar to noble gases by filling their outer most shell)
Fluorine has 7 valence electrons. In order to become stable, Florine will share 1 electron with another atom to get 8 electron and become stable.
Sodium has 11 electrons.
the oxidation number
Yes, The electrons are unequally shared in an Ionic Bond. One atom has more electrons than the other atom. Every Atom has Electrons that are called Valence Electrons. These Valence Electrons are the electrons in the outer shell of the Bohr Model of the atom. There should be a stable number of Valence electrons (2 or 8) for an atom to be completely stable. To stabilize the valence electrons the atom bonds with other atoms. One type of bond is called ionic bond where one atom gives up a certain number of electrons to be stable and another atom gains all of those lost atoms.
One carbon atom will typically share electrons with four other atoms to complete its outer electron shell, achieving a stable configuration. This enables it to form up to four covalent bonds with other atoms.
A covalent bond occurs when an atom shares one or more pairs of electrons with another atom. In this type of bond, the atoms share electrons to achieve a more stable electron configuration.
Atoms become stable by gaining or losing electrons to achieve a full outer electron shell. This involves forming bonds with other atoms to share or transfer electrons. Once the outer shell is full, the atom is more stable and less likely to react with other atoms.
