MCQ
An electronic transition from $1s$ orbital of an atom causes
- ✓Absorption of energy
- BRelease of energy
- CBoth release or absorption of energy
- DUnpredictable
✓
Answer
Correct option: A.
Absorption of energy
a
$1s$ orbital is the very ground state for an atom hence there always be absorption of energy if an electron transition takes place.
