Metals Non-Metals and Metalloids

Metals

• Lose electrons during reactions• Form Ionic Bonds• Over 80% of the elements on the

table• Most metallic elements are at the

bottom of the group

Non-Metals

• Liquids/Gases• Right of Staircase• Gain electrons to form ionic

bonds(negative charges)• Share electrons to form covalent

bonds

Metalloids

• Have properties of both metals and non-metals

• Called semi-metals as well• On the staircase• B, Ge, Si, As, Sb, Te, At)

Metals/Non-Metals/Metalloids

Metals• Solid at Room

Temperature• Density greater than 1• Malleable • Ductile (Bent, Formed)• Luster (Shine)• Conduct Electricity• Low Ionization Energy• Low Electronegativity

Non-metals• Liquid or Gas at Room

Temperature• Density less than 1• Brittle• Not Ductile • No Luster (Dull)• Most Do not Conduct• High Ionization Energy• High Electronegativity

What are the Diatomic Elements? • Elements that are never found alone

in nature• Always part of a compound or

molecule• They are: H2, N2, O2, F2, Cl2, Br2, I2

• Think HOFBrINCl• These are the only elements that

can bond with themselves
