Nettet16. sep. 2024 · Nonmetals. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite). Non-metals can be gases, liquids or solids. NettetThe group 1 of Periodic table follows elements serially as:H,Li,Na,K,Rb,Cs,Fr..Here,clearly Lithium is the least metallic element of group 1.. It's not Hydrogen becoz It's a non-metal..so,Lithium is the correct answer.. NettetThere are 70 different metals charted in the periodic table. Here they are in alphabetical order: Actium.
