An element X which is a 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 the major air pollutants.(a) Identify the element X(b) Write the electronic configuration of X(c) Write the balanced chemical equation for the thermal decomposition of ferrous sulphate crystals?(d) What would be the nature (acidic/ basic) of oxides formed?(e) Locate the position of the element in the Modern Periodic Table.

(a) Element X is Sulphur.
(b) Its electronic configuration is 2,8,6.
(c) The balanced chemical equation for the thermal decomposition of ferrous sulphate crystals is shown below:
$2FeSO_4 \rightarrow Fe_2O_3 + SO_2 + SO_3$
(d) The oxides of Sulphur are acidic in nature.
(e) Sulphur is placed in Group 16 Period 3 of the Modern periodic table.
