Examine the electron orbital diagram provided. Each box represents an orbital, and the arrows represent electrons with their spins. The diagram shows the distribution of electrons in the orbitals.
Count the total number of electrons in the diagram. Each arrow represents one electron. Add up all the arrows to determine the total number of electrons.
Determine the electron configuration based on the orbital diagram. For example, the diagram shows filled 1s, 2s, and 2p orbitals, partially filled 3s and 3p orbitals. Write the electron configuration in the format: \( 1s^2 \ 2s^2 \ 2p^6 \ 3s^2 \ 3p^4 \).
Identify the element based on the total number of electrons. The number of electrons corresponds to the atomic number of the element. Use the periodic table to find the element with this atomic number.
Verify the element by comparing the electron configuration to the expected configuration for the element. The configuration \( 1s^2 \ 2s^2 \ 2p^6 \ 3s^2 \ 3p^4 \) matches sulfur, which has an atomic number of 16.
