Per NCERT Problem 2.1, in ⁸⁰₃₅Br how many neutrons, protons and electrons are present (assuming neutral atom)?
A35 protons, 35 electrons, 35 neutrons
B80 protons, 80 electrons, 35 neutrons
C35 protons, 35 electrons, 45 neutrons
D45 protons, 45 electrons, 35 neutrons
Answer & Solution
Correct answer: C. 35 protons, 35 electrons, 45 neutrons
Per NCERT Problem 2.1, Z = 35 ⇒ p = e = 35; n = A − Z = 80 − 35 = 45.
