Locate the position of Se in the periodic table and use it as a guide to determine the electron configuration of Se
Determine the ground-state electron configuration of Selenium (Se) by locating the position Se in the periodic table.
Ground-state means that the element is in its lowest energy form (not in excited state). Neutral selenium means it has no charge, meaning no electrons are removed or added in the atom.
You see in the above illustration of the periodic table that Se is in Period 4, Group 6A and s-block
Give the full ground-state electron configuration for the element. Se
e. none of these
