Question

Orbits in which electrons move according to Bohr are

(a) Elliptical
(b) Cylindrical
(c) Circular
(d) Oval

Answer 1

Answer:

(c) Circular is the correct option.

Answer 2

Answer:

An orbit is a fixed path along which an electron travels or rotates around an atom's nucleus. In addition, an orbit is a simple planar representation of a certain electron.

Explanation:

Postulates of Bohr Atomic Model:

1. The fixed circular path that electrons take around the nucleus is referred to as an "orbit," "shell," or "energy level."
2. "Stationary orbit" is the name given to the orbits.
3. These circular orbits were known as orbital shells and each circular orbit will have a particular amount of fixed energy. As long as they continue to orbit the nucleus in the defined orbital shells, the electrons won't emit any energy.
4. Integers such as n=1 or n=2 or n=3 are used to represent the various energy levels. We refer to these as quantum numbers. From the lowest energy level (nucleus side n=1) to the greatest energy level, the range of quantum numbers can change.
5. There are two methods to express the various energy levels or orbits, such as 1, 2, 3, 4... or K, L, M, N... shells. The term "ground state" refers to the electron's lowest energy level. 
6. When electrons go from one energy level to another, their energy changes. The electrons in an atom transition from a lower to a higher energy level by collecting the necessary energy. An electron, however, shifts from a higher to a lower energy level as it loses energy.

Thus, the orbits in which electrons move according to Bohr are circular.

While the other shapes of the orbits are incorrect.

The correct option is (c) circular.
