Question

True or False. The spin quantum number (ms) describes the orientation of the spin of the electron. The magnetic quantum number (ml) describes the the size and energy associated with an orbital. An orbital is the path that an electron follows during its movement in an atom. The angular momentum quantum number (l) describes the orientation of the orbital. The principal quantum number (n) describes the shape of an orbital.

Answer 1

The spin quantum number (ms) describes the orientation of the spin of the electron: TRUE

The magnetic quantum number (ml) describes the size and energy associated with an orbital. An orbital is the path that an electron follows during its movement in an atom: FALSE

The angular momentum quantum number (l) describes the orientation of the orbital: FALSE

The principal quantum number (n) describes the shape of an orbital: FALSE

Explanation:

• The magnetic quantum number (ml) - The number of orbitals and the orientation within a subshell is determined.  

• The orbital angular momentum quantum number (l) - The shape of an orbital is determined.

• The principal quantum number (n) - The energy of an electron and the distance of the electron from the nucleus is described.
