Which of the following is the most electropositive element?(a) Phosphorus (b) Magnesium(c) Aluminium (d) Sulphur

Answer»

Correct option (b) Magnesium

Sulphur and phosphorus are non-metals, they have very low electropositivity. As aluminium has one extra-nuclear charge than Mg, it has lesser electropositive character than Mg [due to greater pull exerted by nucleus on e-].
