Question

32/50
which element is the least reactive?
c
ne
li
b

Explanation:

To determine the least reactive element, we refer to the periodic table. Noble gases (like Neon, Ne) have a full valence electron shell, making them very stable and least reactive. Lithium (Li) is an alkali metal, highly reactive. Boron (B) is a metalloid with moderate reactivity. Carbon (C) is a non - metal with more reactivity than noble gases. So Ne is the least reactive.

Answer:

Ne (Neon) is the least reactive element among the given options (C, Ne, Li, B).
