Problem: How many unpaired electrons are there in the ground state electronic configuration of As?A. 2B. 0C. 1D. 4E. 3

FREE Expert Solution

We’re being asked to determine the number of unpaired electron in the ground state electronic configuration of As


Ground-state means that the element is in its lowest energy form (not in excited state). Neutral neon means it has no charge, meaning no electrons are removed or added in the atom.


You can see in the above illustration of the periodic table that As is in Period 4, Group 5A, and p-block.
