PLEASE HELP FAST Question- Since metals prefer to give away electrons during chemical bonding, the most active metals are closest to francium, which is a large atom with low ionization energy and electronegativity. Nonmetals prefer to pull in electrons, so the most active nonmetals are closest to fluorine, which has a high ionization energy and electronegativity. The noble gasses (Group 18) are considered inactive since they already have a stable octet of electrons in their outer shell.
Referring to a periodic table, highlight the member of each pair of elements which is most chemically active.
