Question

question 3 of 10
how does an atom behave if it has a full octet of valence electrons?
a. it is very reactive.
b. it is a gas.
c. it is unpredictable.
d. it is very stable.

Explanation:

Atoms tend to gain, lose, or share electrons to achieve a full octet (eight valence electrons) as it represents a stable electron configuration. Noble gases have full octets and are known for their stability and lack of reactivity under normal conditions. Reactivity (Option A) is low when octet is full. Being a gas (Option B) is a physical state not directly determined by octet. Unpredictable (Option C) is incorrect as full - octet atoms follow stable behavior.

Answer:

D. It is very stable.
