Question

Which of the following element has the strongest tendency to form electrovalent compound?

• A. $Li$
• B. $Na$
• C. $Be$
• D. $Mg$

Answer 1

The correct option is B $Na$

It it can loose this on electron in $3s$ orbital, it will acquire inert gas configuration which is the most stable. Hence, $Na$ would have strong tendency to form electrovalent compound by loosing its valance electron in $3s$ orbital. Thus, it can easily form ${Na}^{+}$, resulting in ionic compounds.
