ELEMENTS

METALS

METALS

• Metals are good conductors of heat and electricity.
• Metals are strong and malleable
• Metals are usually solid

MERCURY

• Only metal in liquid form in room temperature
• mercury is known to be highly toxic, it was considered therapeutic
• Mercury does not react with most acids.

NON METALS

NONMETALS

• poor conductors of heat and electricity.
• they are not ductile: they cannot be easily reshaped.
• broad grouping are the six noble gases,

HALOGEN

• term "halogen" means "salt-former"
• compounds containing halogens are called "salts".
• The halogens exist, at room temperature, in all three states of matter

METALLOIDS

FACTS

• They appear to be metal in appearance, but are brittle.
• They are solids under standard conditions
• They are mostly nonmetallic in their chemical behavior.

ARSENIC

• comes from the Persian word Zarnikh, meaning "yellow orpiment,"
• crystalline metalloid
