Question

5 applications of bohr atomic model

Answer 1

Electrons revolve around the nucleus in a fixed circular path termed “orbits” or “shells” or “energy level.”

The orbits are termed as “stationary orbit.”

Every circular orbit will have a certain amount of fixed energy and these circular orbits were termed orbital shells. The electrons will not radiate energy as long as they continue to revolve around the nucleus in the fixed orbital shells.

The different energy levels are denoted by integers such as n=1 or n=2 or n=3 and so on. These are called as quantum numbers. The range of quantum number may vary and begin from the lowest energy level (nucleus side n=1) to highest energy level. Learn the concept of an Atomic number here.

The different energy levels or orbits are represented in two ways such as 1, 2, 3, 4…  or K, L, M, N….. shells.  The lowest energy level of the electron is called the ground state. Learn the concept of Valency here in detail.

The change in energy occurs when the electrons jump from one energy level to other. In an atom, the electrons move from lower to higher energy level by acquiring the required energy. However, when an electron loses energy it moves from higher to lower energy level

Answer 2

Answer:

By explaining that electrons move in fixed orbitals (shells) and not anywhere in between, Bohr's theory amended the atomic structure model.

Explanation:

• He also showed that each orbit (shell) has fixed energy.
• Bohr refined Rutherford's model of the atom's nucleus to include electrons and their varying energy levels.
• In an atom, negatively charged electrons travel in fixed circular paths around the positively charged nucleus that are referred to as orbits or shells.
• These circular orbits are referred to as orbital shells because each orbit or shell has defined energy.
• The quantum number (n=1, 2, 3, etc.), which is an integer, is used to indicate the energy levels. The lowest energy level in this quantum number range, n=1, lies on the nucleus side. When an electron reaches the lowest energy level, it is referred to as being in the ground state. The orbits n=1, 2, 3, 4... are allocated as K, L, M, N.... shells.
• A lower energy level to a higher energy level is reached by an atom's electrons by gaining the necessary energy, and a higher energy level to a lower energy level by losing energy.

For substances that are similar to hydrogen but only have one electron, Bohr's hypothesis is relevant.
