An element 'X' belongs to 3rd period and group 16 of the Modern Periodic table.
a) Determine the number of valence electrons and the valency of 'X'
b) Molecular formula of the compound when 'X' reacts with hydrogen and write it's electron dot structure
c) Name the element 'X' and state whether it is metallic or non- metallic
Dear Student,
Please find below the solution to the asked query.
The element belongs to group 16 and period 3.
1) Number of vakence electrons = 6
Valency = 8-6 = 2
2) Molecular formula of the compound formed by X and H will be H2X
Dot structure will be:
3) The element 'X' is Sulphur and it is non-metallic.
