Question

The radius r of a hydrogen atom can only depend on:_____

Answer 1

The radius of a hydrogen atom can only depend on the principal quantum number (n) and the Bohr radius (aB).

Step-by-step explanation:

The radius r of a hydrogen atom can only depend on two factors:

1. The principal quantum number (n): The value of n determines the energy level or orbit of the electron. The radius of the orbit increases with increasing n value.
2. The Bohr radius (aB): It is a constant value for hydrogen and is approximately equal to 0.529 x 10^-10 meters. The Bohr radius sets the overall scale of the atom and determines the size of the orbits.
