Lithium has a charge of 1+ and a total number of 3 valence electrons
Everything to the left of the metalloids (the staircase that separates the metals and the non-metals in the periodic table) can be considered a metal, with the exception of hydrogen. Metals are solid at room temperature(with the exception of mercury which is a liquid element), shiny, ductile, malleable, and good conductors of electricity and heat. Metals tend to lose electrons easily. Generally speaking metals have a large atomic radius, low ionization energy, and low electronegativity. These properties are all the a result of the fact that the electrons in the valence shell of metal atoms can be removed with great ease.
SOME elements in the periodic table are neither metals nor non-metals. These are classified as metalloids and form a staircase beside the non-metals. Metalloids are also referred to as semi-metals.
