Answer:
The energy of third Bohr orbit the hydrogen atom is -145.7kJ/mol.
Explanation:
According to Bohr's theory, the total energy of an electron in the nth orbit is directly proportional to the square of the number of protons and inversely proportional to the square of the principal quantum number.
i.e., Eₙ ∝ z²/n²
for a hydrogen atom, z=1
Given that,
E₂ = -328kJ/mol.
we have to find the energy of the third orbit E₃,
Hence, the energy of third Bohr orbit is -145.7kJ/mol.
Here, option 4 should be the correct one (nearest to -146kJ/mol. )
