Bohr model is ______.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Bohr model of Atom
The Bohr model, put forward by Niels Bohr in 1913, is a model of the atom. In it, electrons move round the nucleus only in certain fixed circular orbits (shells or energy levels) and do not lose energy while they stay in one; an electron gives out or takes in energy only when it jumps from one orbit to another. The model explained the line spectrum of hydrogen.
