Question

what element is designated by the orbital diagram below?
orbital diagram: 1s with two opposite - spin electrons, 2s with two opposite - spin electrons, 2p with two orbitals having two opposite - spin electrons each and one orbital having one electron (spin up)

Explanation:

Step1: Count electrons per orbital

1s: 2 electrons; 2s: 2 electrons; 2p: 3 electrons

Step2: Calculate total electrons

Total electrons = $2 + 2 + 3 = 7$

Step3: Match to element

Neutral element has protons = electrons = 7, which is nitrogen.

Answer:

Nitrogen (N)
