How are metalic bonding and ionic bonding similar?

Answer 1

Metallic bonds have only a superficial resemblance to ionic bonds.

One very simple model describes metals as positive ions in a sea of electrons and while this rationalises the electrical conductivity of metals it does not explain why the metals generally have high melting points.

The force that holds the lattice together is not a simple electrostatic force as in an ideal ionic lattice. In most metals some of the bonding derives from some covalent bonding between metal atoms allied with delocalised bonds occupied by free electrons.

Different models that are used are

Band theory - considering the metal lattice as a fixed lattice of positive charges and then applying a similar approach as used for the hydrogen atom - a single charged nucleus with 1 electron. This model predicts bands of "orbitals" of similar energy which are delocalised.

Molecular orbital theory / valence bond theory which employ the same techniques as used by chemists for molecues. This also predicts delocalised orbitals.
