Final answer:

The quantum numbers n, l, and ml are critical in determining the energy, shape, and orientation of the electron's orbital in a hydrogen atom. The principal quantum number n is tied to the energy, l to the orbital shape, and ml to the orbital orientation. Heisenberg's uncertainty principle also plays a role in the behavior of the electron within the atom.

Step-by-step explanation:

Understanding the Quantum Numbers of a Hydrogen Atom

The question asks about the quantum numbers associated with the states of a hydrogen atom. Quantum numbers n, l, and ml (ignoring the electron spin) uniquely specify the state of an electron in a hydrogen atom. The wavefunction of an electron, which can be expressed as a product of radial and angular functions, is linked with these quantum numbers that determine the electron's properties such as energy and angular momentum.

The principal quantum number n corresponds to the electron's energy level. For instance, the ground state of hydrogen (1s state) has n = 1, indicating the lowest energy state. The angular momentum quantum number l is associated with the shape of the atomic orbital, where for n = 1, l must be zero, signifying an s orbital with spherical symmetry.

Moreover, the magnetic quantum number ml helps in determining the orientation of the orbital in space. Notably, for a given value of n, l can have integer values from 0 to n-1 and for each value of l, ml can range from -l to l. The quantum number s is for the spin angular momentum and ms represents its projection. For the spin, these two quantum numbers are +1/2 and -1/2, indicating spin-up and spin-down states.

Heisenberg's uncertainty principle argues that the electron's position and momentum cannot be precisely determined simultaneously, influencing the electron's presence within the atom and preventing its collapse into the nucleus.
