Summary of HC Verma Solutions Part 2 Chapter 43: Bohr's Model and Physics of the Atom
FAQs on HC Verma Solutions Class 12 Chapter 43 - Bohr's Model and Physics of Atom
1. What is Bohr’s model of Atom called ?
Bohr has explained that electrons can be moved into different orbits with the inclusion of energy. When the energy is separated and removed, the electrons return back to their ground state, emitting a corresponding amount of energy -- a quantum of light. This was the basis quantum theory, as we know now.
2. What is Bohr’s model used for ?
The Bohr model is used to d electrons in Atoms are in orbits of different energy around the nucleus .. Bohr used the term energy levels (or shells) to display orbits of differing energy. He said that the energy of an electron is quantized, referring that electrons can have one energy level or another but nothing in between.
3. What was the Bohr experiment ?
The Bohr model shows the Atom as a small, positively charged nucleus surrounded by orbiting electrons. Bohr was the first to find out that electrons travel in separate orbits revolving around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.
4. How did Bohr explain the stability of Atoms ?
Niel Bohr explained the stability of the Atoms with the concept of revolution of electrons in different energy levels. The change in the energy of an electron happens when the lower energy level gets shifted to a higher energy level or vice-versa. In this way, energy is not lost and the Atom stays stable.
5. How was the Bohr model discovered ?
Niel Bohr proposed a theory for the hydrogen Atom in 1913, which was based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, and if the electrons move around a nucleus, but only in prescribed orbits, and if electrons jump to a lower energy orbit, the difference is sent out as radiation.
