Question

why do noble gases typically not react with other elements chemically?
a because they have more protons than other elements
b because they have fewer neutrons than other elements
c because they have a full outer shell of valence electrons
d because they have a single valence electron in their outer shell

Explanation:

Noble gases are stable due to full outer - shell of valence electrons, reducing reactivity.

Answer:

C. because they have a full outer shell of valence electrons
