Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Niels Bohr suggested that electrons ____
A
are found in specific orbits
B
electrons are scattered throughout the atom
C
electrons move according to their energy level
D
electrons are positive
Explanation: 

Detailed explanation-1: -Bohr suggested the revolutionary idea that electrons “jump” between energy levels (orbits) in a quantum fashion, that is, without ever existing in an in-between state. Thus when an atom absorbs or gives off energy (as in light or heat), the electron jumps to higher or lower orbits.

Detailed explanation-2: -In Bohr’s model, electrons exist in orbits around the nucleus which only exist at fixed distances from the nucleus called levels. In Bohr’s atomic model, electrons move around the nucleus only at fixed distances from the nucleus based on the amount of energy they have.

Detailed explanation-3: -What was Niels Bohr’s most important discovery? Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus.
