Answer:

The correct option is an atom with a partly filled energy level

Explanation:

An atom with a partially filled energy level means the atom has a partially filled outermost shell which in turn means the atom as valence electrons. The presence of valence electrons in atoms makes them undergo chemical bonding with other atoms of the same/different elements (during chemical reactions).

Atoms with completely filled energy levels (such as the noble gases) have a completely filled outermost shell and hence do not have valence electrons which can take part in bond formation during chemical reactions and hence these group of atoms have low chemical reactivity.

It is more reactive the atom with a partly filled energy level because is less stable than the other case. Stability is inversely proportional to reactivity.

Why is the Lithium ion (Li+1) stable even though it does not have an octet?
Elan Coil [88]
I think Lithium, an alkali metal with three electrons, is also an exception to the octet rule. Lithium tends to lose one electron to take on the electron configuration of the nearest noble gas, helium, leaving it with two valence electrons. There are two ways in which atoms can satisfy the octet rule
