b. size of the orbital
c. spin of electron
d. orientation of in the orbital electron cloud​

Answer 1

Answer:

Option a. shape of orbital

Explanation:

The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in. The number of subshells, or l, describes the shape of the orbital.
