Verified step by step guidance

Examine the given electron orbital diagram. Each box represents an orbital, and the arrows represent electrons with their spins.

Count the total number of electrons represented in the diagram. Each arrow represents one electron.

Identify the electron configuration based on the diagram. The order of filling is 1s, 2s, 2p, 3s, 3p, etc.

Match the electron configuration to the corresponding element on the periodic table. The number of electrons should equal the atomic number of the element.

Compare the identified element with the options provided: Silicon, Fluorine, Sulfur, Chlorine, and Phosphorus, to determine which one matches the electron configuration.
