Question

which family of the periodic table has the greatest stability because they fulfill the octet rule?
a. halogens
b. noble gases
c. carbon family
d. alkali metals

Explanation:

The octet rule states that atoms tend to gain, lose, or share electrons to have 8 electrons in their valence shell. Noble gases already have a full valence shell (8 electrons, except helium which has 2 in its only shell), making them very stable. Halogens have 7 valence electrons and tend to gain 1 electron. The carbon family has 4 valence electrons and can form various bonds. Alkali metals have 1 valence electron and tend to lose it.

Answer:

B. Noble Gases
