Question

What is the trend of energy of Bohr’s orbits?
A) Energy of the orbit increases as we move away from the nucleus.
B) Energy of the orbit decreases as we move away from the nucleus.
C) Energy remains the same as we move away from the nucleus.
D) Energy of Bohr’s orbit cannot be calculated.

Answer 1

Hint: Bohr’s atomic model is a modification for Rutherford’s atomic model. Bohr’s atomic model explains that the electrons move in a fixed orbital around the nucleus and also the energy of the orbit according to its location from the nucleus.

Complete step by step answer:
1) First of all let's learn about the concept of Bohr’s atomic orbital where it is the modification of Rutherford’s atomic model. Bohr’s atomic model explains as a small nucleus that is positively charged, surrounded by negatively charged electrons that are moving in orbits around the nucleus.
2) Bohr found out by experiments that an electron that is situated far from the nucleus has more energy, and electrons which are situated close to the nucleus have less energy.
3) Bohr has modified Rutherford’s atomic structure model by elaborating the concept that electrons move in fixed orbitals that are shells and they do not present anywhere in between the space present in two orbitals. Bohr also explained that each orbit that is the shell has a fixed energy level according to its location from the central nucleus.

Therefore, the trend of the energy of Bohr’s orbits is the energy of the orbit increases as we move away from the nucleus which shows option A as the correct choice.

Note:
Rutherford’s atomic model only explained the nucleus of an atom and Bohr’s atomic model modified Rutherford’s atomic model into electrons and their energy levels. Bohr also explains the movement of electrons in an atom as the electrons move from lower energy to higher energy they gain energy and while moving from higher to lower they lose energy.
