Chemistry

Question Analysis
This question involves the fundamental reason atoms form chemical bonds. The main focus is on the relationship between electron configuration and atomic stability.

Key Concept Explanation
Atoms form chemical bonds (ionic, covalent, metallic) through two main electron behaviors (electron transfer, electron sharing), both of which aim to complete the outer electron shell.

Option Analysis
Option A: To gain valence electrons → Not always true; atoms may gain, lose, or share electrons.
Option B: To create a new element → Chemical bonding does not change elemen...
