### Maximum amount of bonds

What is the maximum amount of bonds an element can have? I know phosphorus can have five and sulfur can have six as they can use the d orbital to have more than four bonds, but how do we know when an element has too many bonds?

An element has too many bonds when the formal charge is unreasonably high. It should be relatively close to zero.

What is considered unreasonably high?

Usually the central atom doesn't have a high formal charge. It depends what the charge is of the full compound. If the compound is neutral then the central atom should have a formal charge of 0 or a formal charge that cancels out the formal charge of the other atoms.

Is it possible for an element in the 3s have more than an octet? this being sodium and magnesium. I am asking due to the fact that they do not have a 3d shell.

It depends on the element. To calculate bond order in chemistry, subtract the number of the electrons in the anti-bonding molecules from the number of electrons in the bonding molecules. Then, divide the result by 2. The higher the bond order, the more stable the molecule.
