Give reasons for the following:
Phosphorus, sulphur and chlorine are electronegative elements of the periodic table.
Answer
Phosphorus, Sulphur and Chlorine are the rightmost elements of period 3 in the periodic table. Across a period from left to right electronegativity increases as nuclear charge increases and atomic size decreases. This makes Phosphorus, Sulphur and Chlorine electronegative elements of the periodic table.
