Which Elements Are Likely to Lose Electrons?

The most metallic elements are Cesium and Francium

. Metals tend to lose electrons to attain Noble Gas electron configuration. Groups 1 and 2 (the active metals) lose 1 and 2 valence electrons, respectively, because of their low Ionization energies.

Which elements are most likely to lose electrons?

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.

Which elements are likely to gain electrons?

Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions.
