Answer: 1s² 2s² 2p⁶ 3s² 3p⁶

: This rule serves as a visual guide to the order of orbital filling. To follow it, you move down along an arrow until you reach the end, then move to the start of the next arrow to the right. This explains why fills before fills before The Gizmo provides feedback stating "Electrons not placed

Activity C introduces the (also known as the Aufbau principle's filling order), which dictates that electrons fill lower-energy subshells before moving to higher ones. A common "trick" students encounter in this activity is that the 4s subshell fills before the 3d subshell , despite 3 being a lower shell number than 4. Activity C Step-by-Step Walkthrough To follow it, you move down along an

: Electrons will occupy empty orbitals in a subshell individually before pairing up (similar to passengers finding their own seats on a bus).
