identify the element in period 3 that requires the least amount of energy to remove the most loosely held electrons from a mole of gaseous atoms of the element in the ground state.

Determine the electron geometry (eg) and molecular geometry (mg) of CO2. eg=trigonal planar, mg=trigonal planar eg=linear, mg=linear eg=tetrahedral, mg=tetrahedral eg=trigonal planar, mg=bent eg=linear, mg=trigonal planar
