Answer: 18.

A 17
B 18
C 35
D 52

Correct answer: B. 18

Explanation: Neutrons = mass number - atomic number = 35 - 17 = 18.

Bohr's model: electrons occupy fixed circular shells (K, L, M) around the nucleus, with each shell holding up to 2n² electrons.

Concept context

Explore how electrons are arranged inside an atom. Covers Bohr's model, quantum numbers, Heisenberg's uncertainty principle, shapes of s, p, d orbitals, and electronic configuration rules.
