Markscheme
Accept all 2p electrons pointing downwards.
Accept half arrows instead of full arrows.
Examiners report
Drawing arrows in the boxes to represent the electron configuration of a nitrogen atom was done extremely well.
Syllabus sections
Structure 1. Models of the particulate nature of matter » Structure 1.3—Electron configurations » Structure 1.3.5—Each orbital has a defined energy state for a given electron configuration and chemical environment, and can hold two electrons of opposite spin. Sublevels contain a fixed number of orbitals, regions of space where there is a high probability of finding an electron. Apply the Aufbau principle, Hund’s rule and the Pauli exclusion principle to deduce electron configurations for atoms and ions up to Z = 36.
