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.
