VESPR theory counts how many 'groups' of electrons VESPR theory counts how many 'groups' of electrons are around the central atom. VESPR theory counts how many 'groups' of electrons A bond counts as one 'group' are around the central atom. VESPR theory counts how many 'groups' of electrons A bond counts as one 'group' It doesn't matter whether is it single, are around the central atom. VESPR theory counts how many 'groups' of electrons A bond counts as one 'group' It doesn't matter whether is it single, double, are around the central atom. VESPR theory counts how many 'groups' of electrons A bond counts as one 'group' It doesn't matter whether is it single, double, or triple are around the central atom. VESPR theory counts how many 'groups' of electrons A bond counts as one 'group' It doesn't matter whether is it single, double, or triple are around the central atom. bond. VESPR theory counts how many 'groups' of electrons A bond counts as one 'group' It doesn't matter whether is it single, double, or triple It still counts as ONE group! are around the central atom. bond. This atom has three bonding groups. N This atom has three bonding groups. 1 N This atom has three bonding groups. 1 N 2 This atom has three bonding groups. 1 N 2 3 This atom also has three bonding groups. C This atom also has three bonding groups. 1 C This atom also has three bonding groups. 1 C 2 This atom also has three bonding groups. 1 C 2 3 How many groups? 1 2 3 4 O How many groups? 1 2 3 4 N How many groups? 1 2 3 4 O How many groups? 1 2 3 4 C Lone electron pairs also act as 'groups'. Lone electron pairs also act as 'groups'. Ne Lone electron pairs also act as 'groups'. Each 'pair' acts as a group. Ne Lone electron pairs also act as 'groups'. Each 'pair' acts as a group. 1 Ne Lone electron pairs also act as 'groups'. Each 'pair' acts as a group. 1 Ne 2 Lone electron pairs also act as 'groups'. Each 'pair' acts as a group. 1 Ne 3 2 Lone electron pairs also act as 'groups'. Each 'pair' acts as a group. 4 1 Ne 3 2 Lone electron pairs also act as 'groups'. So this atom has 4 electron pair groups. Each 'pair' acts as a group. 4 1 Ne 3 2 How many electron pair groups? O How many electron pair groups?
