Bonding pair
Two electrons shared between two atoms in a covalent bond
Two electrons shared between two atoms in a covalent bond
Bonding pair
Electron pair repulsion theory
When electron pairs are negatively charged, they repel each other
They are arranged to minimise repulsion and maximise separation
When electron pairs are negatively charged, they repel each other
They are arranged to minimise repulsion and maximise separation
Electron pair repulsion theory
Dative covalent bond
When an atom supplies both electrons in the formation of a covalent bond
When an atom supplies both electrons in the formation of a covalent bond
Dative covalent bond
