Step-by-step explanation:

Lithium's low reactivity is due to the proximity of its valence electron to its nucleus (the remaining two electrons are in the 1s orbital, much lower in energy, and do not participate in chemical bonds). However, molten lithium is significantly more reactive than its solid form.
