An atom is chemically inert if its outermost shell has two pairs of electrons.

Question

Quizplus · Accepted Answer

An atom is considered chemically inert if its outermost shell, also known as valence shell, is completely filled with electrons. For the majority of elements, this means there should be eight electrons in the valence shell, except for hydrogen and helium which only require two electrons. Therefore, an atom with two pairs of electrons in its outer shell is not necessarily inert, as it still has space for additional electrons to fill the valence shell.
