Answer:

#4#

Explanation:

You can calculate the number of orbitals present on a given energy level #n# by using the equation

#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 #n=2#, will have a total of

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

The second energy level will thus have a total of #4# 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 orbital in the s-subshell: #2s#
  • three orbitals in the p-subshell: #2p_x#, #2p_y#, #2p_z#

Since each orbital can hold a maximum of #2# electrons, you an say that the second energy level can hold a maximum of

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