Question

Use the periodic table to answer the following questions.

(B) Identify an element that would tend to lose two electrons.

Answer 1

Element that would tend to lose two electrons

An element having two valence electrons will lose two electrons easily to attain the stable noble gas configuration. The general electronic configuration of such an element will be $n{s}^2$. This is the electronic configuration of group $2$ elements. The elements present in group $2$ are $Be\left(2s^2\right),Mg\left(3s^2\right),Ca\left(4s^2\right),Sr\left(5s^2\right),Ba\left(6s^2\right),Ra\left(7s^2\right)$.
