1
Q
covalent bond
A
the electrostatic attraction between a shared pair of electrons and the nuclei of bonded atoms
2
Q
co-ordinate bond
A
a shared pair of electrons between two atoms. one atom provides both the electrons
3
Q
octet rule
A
when reacting, an atom tends to gain, lose or share electrons to achieve eight in its outer shell
4
Q
electronegativity
A
the extent to which an atom attracts the bonding electrons in a covalent bond
5
Q
polar bond
A
a covalent bond is which there is an unequal sharing of the bonding electrons
6
Q
