Question

the elements w, x, y and z have atomic numbers 7, 9, 10 and 11 respectively. write the formula of the moleculea that would be formed between the following pairs of elements and indicate the type of the bounding present using (•) and crosses (x) to represent valence electrons. a) w and x b) x and x c) w and z d) y and y​

Answer 1

Answer:

a) w and x have valency 3 and 1 respectively

Thus compound will be w × 3x, 1:3 i.e., wx3 ●3 single bonds

b) x and x will be x × x, 1:1 i. e., x2 ● A single bond

c) w and z have valency 3 and 1 respectively

Thus compound will be w × 3z, 1:3 i.e., wz3 ●3 single bonds

d) y and y will be y × y, 2:2 i.e., y2 ●A double bond

hope this will help you
