Metal
a substance made when two or more metals are combined or when a metal and a nonmetal are united.
▪Metal alloy
A substances, ability to be flattened, into sheets.
Malleability
naturally occurring rock, from which a useful metal or mineral is recovered.
▪Ores -
the elements in group 1A on the periodic table Have 1 valence electron
▪Alkali metals -
group 2 on the periodic table, beryllium, magnesium, calcium, strontium, barium, and radium.
▪Alkaline – earth metals –
an element that is usually hard and shiny conducts, electricity, and heat, and has a higher melting point.

two
force of attraction between the metal atoms in the surrounding sea of electrons in the metal
▪Metallic bond
the gradual, wearing away of a metal as a result of a chemical reaction
