What is Ionic Covalent Hydrogen Metal Bond?
Ionic bonding is due to electrostatic attraction between ionic completed electron shells. It does not have a definite spatial direction, since each ion is associated with a certain number of counterions in accordance with the coordination number.
If the difference in the electronegativity of the elements that form the bond is large (more than 2), then the bond is ionic, in the other case – covalent.
A covalent bond is formed by the sharing of electrons of bound atoms.
A hydrogen atom bound to strongly electronegative atoms (fluorine, nitrogen, oxygen, chlorine) is able to interact with a lone pair of electrons of another strongly electronegative atom of the same or another molecule to form an additional bond called hydrogen.
A metallic bond is a bond between atoms in a metal crystal, arising from the socialization of their valence electrons.
