Each row on the periodic table represents:

• an energy level

• a sublevel

• an electron

• an orbital

Is the following electron configuration correct? Why or why not?

1s²2s²2p⁶3s²3p⁶4s²4d¹⁰4p⁶5s¹

• No. 4p⁶ should be after 5s¹.

• No. It should be 3d¹⁰ not 4d¹⁰

• Yes. All electrons are represented properly.

• Yes.
