Question

The subshell letter:a) specifies the 3-D shape of the orbital.b) specifies the principal shell of the orbital.c) specifies the principal quantum number of the orbital.d) specifies the maximum number of electrons.e) none of the above

Answer 1

The subshell letter specifies the principal shell of the orbital and not the 3-D shape, principal quantum number, or maximum number of electrons.

Step-by-step explanation:

The subshell letter specifies the principal shell of the orbital. Each shell has subshells equal to the shell number. For example, the 1st shell has one subshell, which is designated as 1s. The 2nd shell has two subshells, 2s and 2p. The 3rd shell has three subshells, 3s, 3p, and 3d. And the 4th shell has four subshells, 4s, 4p, 4d, and 4f. The subshell letter does not specify the 3-D shape of the orbital, the principal quantum number of the orbital, or the maximum number of electrons.

Answer 2

a) specifies the 3-D shape of the orbital

Step-by-step explanation:

To determine the region where is more probable to find the electron, it is characterized by four quantum numbers:

- Principal quantum number (n): represents the level, or shell, where the electron is. It varies from 1 to 7, and are represented by the letters K, L, M, N, O, P, and Q.

-Azimuthal quantum number (l): represents the sublevel, or subshell. Is represented by the letters s, p, d, f, g, ... And by the numbers 0, 1, 2, 3, ... Each one has a 3-D shape, the s, for example, has a spherical shape.

-Magnetic quantum number (ml): represents the orbital inside the subshell, and varies from -l to +l, passing by the 0. Each orbital can have at least 2 electrons.

-Spin quantum number (ms): represents the spin of the electron, which can be +1/2 or -1/2.
