#### Explanation:

You can calculate the **number of orbitals** present on a given *energy level*

#color(blue)(|bar(ul(color(white)(a/a)"no. of orbitals" = n^2color(white)(a/a)|)))#

In this case, the second energy level, which is characterized by

#"no. of orbitals" = 2^2 = 4#

The second energy level will thus have a total of **orbitals**. These orbitals will be distributed on **two subshells**, the s-subshell and the p-subshell.

You can thus say that the second energy level will contain

one orbitalin the s-subshell:#2s# three orbitalsin the p-subshell:#2p_x# ,#2p_y# ,#2p_z#

Since each orbital can hold a *maximum* of **electrons**, you an say that the second energy level can hold a maximum of

#"2 e"^(-)"/orbital" xx "4 orbitals" = "8 e"^(-)#
