Question

Which of these statements about Bohr's model of the atom is correct?

a.The greater the quantum number the higher the energy of an orbit.
b.Elements with the same number of electrons in their outer orbit have similar
properties.
c.All of these statements are correct.
d.Electrons occupy orbits with certain radii corresponding to discrete energies.
e.Electrons fill lower energy orbits first.

Answer 1

The correct answer is that the quantum number reflects an electron's energy, with higher quantum numbers being associated with higher energy orbits. Bohr's model describes electrons in fixed orbits with discrete energy levels and accurately predicts the emission spectra of hydrogen atoms, the correct option is A).

Step-by-step explanation:

The correct statement about Bohr's model of the atom is that the greater the quantum number the higher the energy of an orbit. Conceptually, Bohr's model treats electrons as occupying specific orbits around the nucleus of an atom, which are analogous to the rungs on a ladder.

Each orbit corresponds to a specific energy level, and an electron must absorb or emit a specific amount of energy to move between these orbits. The assumptions of Bohr's model allow it to accurately predict the emission spectra of single-electron atoms such as hydrogen.

However, Bohr's model cannot accurately predict the emission spectra of more complex atoms like neon, and it does not account for the fact that electrons do not actually travel in fixed orbits but are found in regions of probability described by quantum mechanics.
