Metals
 Over
of elements are metals
 Located to the
and
parts of periodic table

Metals - Properties
 Lustrous / Shiny
 Conduct heat
 Conduct electricity
 Malleable
 Ductile
 Usually solids @ room temp

Metals
 Metals tend to lose electrons when they react to form CATIONS
 Metals are mixed with other metals to form
ALLOYS

Cation – an ion with a positive charge

Nonmetals
 Found in the UPPER RIGHT part of the table
 Atoms tend to gain electrons when they react to form ANIONS
 Anion – an ion with a negative charge

Nonmetals Properties
 Solid, liquid or gas @ room temp
 poor heat and electrical conductors
 Good Insulators
 Solids are brittle

Metalloids
 Also called SEMI-METALS
 Found on table between METALS and NONMETALS
 Exhibit characteristics of both metals and nonmetals
 Ex) Silicon, Arsenic, Germanium
