What is a covalent bond?
Electrons shared between 2 nuclei
What is a polar covalent bond? (2)
Polar bond between atoms due to unequally shared electrons
This is caused by differences in electronegativity
What is ionic with covalent character? (2)
Ionic bonding with a degree of polarisation
This causes covalency
What is an ionic bond? (2)
Electrostatic forces of attraction between oppositely charged ions
This causes electrons to be transferred from a metal to a non-metal
Non-polar covalent bond
Electronegativity difference is less than 0.5 (between 0.0-0.5)
Polar covalent bond
Electronegativity difference is 0.5-1.6
Ionic bond with covalent character
Electronegativity difference is between 1.6-2.0
Ionic bond
Electronegativity difference is greater than 2.0
