Per NCERT, how is a HYDROGEN MOLECULE (H₂) formed?
AHydrogen exists only as single atoms
BTwo hydrogen atoms each share their single electron — forming a shared pair that completes both K-shells (2 electrons each)
COne hydrogen atom donates its electron to another
DHydrogen molecules form by losing protons
Answer & Solution
Correct answer: B. Two hydrogen atoms each share their single electron — forming a shared pair that completes both K-shells (2 electrons each)
Per NCERT §9.4.1 A, two H atoms share 1 electron each = duplet completion. The other options misstate.
