Electrons can only orbit the nucleus in _____.
Electrons prefer to orbit in the shell _____.
Each shell can only hold a specific number of electrons
The 1st shell can hold _____.
The 2nd shell can hold _____.
The 3rd shell can hold _____.

BOHR POSTULATE

Let’s have a look at bohrs postulates to answer the question, (bohrs model was applicable only for hydrogen like species)
- Electron revolves around the nucleus in a fixed circular orbit.
- The energy of electron revolving around nucleus doesn’t change with time i.e. it have definite energy.
- The angular momentum of electron(mvr) is integral multiple of h/2π.
- The electron may jump from one energy level to other by absorption or emission of energy.
Now coming to your question,
[tex] \quad \qquad \qquad[/tex] The Bohr Model
Electrons can only orbit the nucleus in a fixed circular orbit.
Electrons prefer fo orbit in the shell which are close to nucleus or having less energy.
Each shell can only hold a specific number of electrons given by formula 2n² where n is the number of shell,
- The 1st shell can hold 2n² = 2×1² = 2 electrons
- The 2nd shell can hold 2×2² = 8 electrons
- The 3rd shell can hold 2×3² = 18 electrons
An atom can gain or lose electrons to form an ion.
