Question

There are three elements X, Y and Z having atomic numbers of 6, 16 and
19 respectively. Based on this information give answer the following
questions:
(a) In which group of the periodic table would you expect to find
(1) element X (II) element Y and (III) element Z?
(B) Which two elements will form ionic bonds? Why?
(C) What will be the formula of ionic compound formed?
(D) What will be the formula of covalent compound formed?​

Answer 1

Answer:

Explanation:A) 1. element X is present in the 14th group

2. Element Y is present in the 16th group

3. Element Z is present in the 1st group.

B). Element Y and element Z will form ionic bonds because here 1 is a metal and another is an non-metal.

In X it cannot take place because it's valency is 4.

C). The formula will be YZ2 as the valency of Y is 2 while of Z is 1.

D)  the covalent compound when formed between element X and y will be XY2 and between elements x and Z will be XZ4.
