Subshells of the Hydrogen Atom (a) Without referring to Table 6.2, predict the number of subshells in the fourth shell, that is, for . (b) Give the label for each of these subshells. (c) How many orbitals are in each of these subshells?

Step 1 of 4

According to the Bohr model, an orbit is described using a single quantum number, n. According to the quantum mechanical model, three quantum numbers, n, l, and, describe an orbital.

Among the three quantum numbers, the first quantum number denoted as n is the principal quantum number. The value of n includes positive integral values like 1, 2, and 3.

The second quantum number denoted as l is the angular momentum quantum number. The value of l varies from 0 to n-1.

The magnetic quantum number, denoted as possesses values between –l to +l. The orbital’s orientation in space is expressed using this quantum number.
