Question

An element 'X' which is yellow solid at room temperature shows catenation and allotropy, 'X' forms two oxides which are also formed during the thermal decomposition of ferrous sulphate crystals and are major air pollutants .

(a) identify element 'X'

(b) write electronic configuration of 'X'

(c) identify the two oxides

(d) what would be the nature of the oxides formed?

(e) what are the valencies of 'X' in these oxides?

(f) locate the position of element 'X' in the Modern Periodic Table.

Answer 1

x is sulphur
electronic configuration is 2, 1, 6 oxides of Sulphur dioxide and sulphur trioxide nature is acidic valency of X is 2
