each atom in the table below, write down the subshell from which an electron would have to be removed to make a +1 cation, and the subshell to ctron would have to be added to make a -1 anion. e first row has been completed for you. subshell from which electron removed to form +1 cation subshell to which electron added to form -1 anion atom H 1s 1s Na Hg Sr

Choose the true statement(s) below concerning the electron affinity of sodium and chlorine. Please note: There may be more than one correct statement. More energy is released when sodium gains and electron than when sodium gains and electron. Sodium has a higher electron affinity than chlorine. Chlorine has a higher electron affinity than sodium. Chlorine wants to gain an electron to form CI™. Sodium wants to gain an electron to form Na™. More energy is released when chlorine gains an electron than when sodium gains an electron. More energy is released when sodium loses an electron than when chlorine gains an electron.
