because they already have 8 valence electrons (or 2 in heliums case) in their outer shell. They don't need anymore electrons
Covalent bonding does not necessarily require that the two atoms be of the there is good overlap between the atomic orbitals of participating atoms.
In almost any case four covalent or polar-covalent bonds are formed. Never ionic!
When atoms are bonded together with covalent bonds, the result is a molecule.
In covalent bonds, electrons are shared. In ionic bonds, electrons are transferred.
Carbon atoms are fixed into organic compounds in The Calvin Cycle.
Carbon will almost always form bonds with other carbon atoms, and that is part of what makes it such a useful element.

No That particular pair of atoms is almost completely ionic. Potassium Bromide has maybe one in a billion covalent bonds.
Carbons almost always form covalent bonds.
The covalent bonds are their role in combining atoms Is In Your Facee ;D

Covalent bonds hold atoms together. Ionic bonds hold ions together
In covalent bonds, electrons are shared. In ionic bonds, electrons are transferred.
covalent bonds.
Coordinate covalent bonds (dative bonds) are covalent bonds where both electrons being shared are coming from the same atom. This being the case, two similar or same atoms will not participate in such a bond because there is no difference to determine which atom should contribute both electrons.
The bonds are ionic or covalent.
