Energy Levels, Orbitals, Spin Quantum Numbers

If an electron has a spin quantum number (ms) of +½, what is the MOST LIKELY spin of its paired electron in the same orbital?

• It must also have a spin of +½.

• It must have a spin of -½.

• It could have either +½ or -½ spin.

• It is impossible to determine without knowing the other quantum numbers.

Which of the following includes ALL the ways quantum numbers describe electrons in an atom?

• distance from the nucleus, shape, and energy

• distance from the nucleus, shape, orientation, and spin

• shape, orientation, and energy

• energy, size, and spin

The principal quantum number (n) primarily determines:

• the shape of the orbital

• the orientation of the orbital

• the energy level of the electron

• the spin of the electron

An electron with n = 3 is compared to an electron with n = 1. The electron with n = 3 will, on average, be:

• closer to the nucleus

• farther from the nucleus and have a larger orbital

• in the same energy level

• impossible to determine
