Question

Which one of the following is the most electropositive element?

• A. Sodium
• B. Magnesium
• C. Aluminium
• D. Silicon

Answer 1

The correct option is A

Sodium

Electropositivity is the ability of elements (mainly metals) to donate electrons to form positive ions. The given elements belong to the same period of the modern periodic table. Along the period, the electropositivity of the elements decreases from left to right. Sodium is present in the first group of the modern periodic table, hence, it is more electropositive than the other given elements.
