THE METAL!!!

PROPERTIES OF METAL• Physical Properties

• Shininess: how well does it reflect light• Malleability: Hammered or rolled into flat sheets and

other shapes.• Ductility: Can be pulled or drawn out into long wire.• Conductivity: Ability to transfer heat or electricity to

another object.

PROPERTIES OF METAL• Chemical Properties

• Reactivity: ease and speed an element combines or reacts with other elements or compounds.

• Corrosion: Destruction of a metal through reaction

THE ALKALI METAL!!!

THE ALKALI METAL!!!• Metals in Group 1

• From Lithium to Francium

• React by losing an electron

• Found only in compounds• Can only be separated

in a lab• Shiny and soft

EARTH ALKALI METALS!!!

• Group 2 = Alkaline Earth Metals• Beryllium to Radium• Hard, grayish-white,

good conductor for electricity

• React by losing two electrons

• Like group 1, never found uncombined in nature

TRANSITION METALS!!!• Groups 3 through 12 =

Transition Metals• Most are hard and

shiny• Good conductors of

electricity• Many form colorful

compounds• Less reactive than

group 1 & 2

MIXED METALS!!!• Some are in Groups 13 through 15

• Not as reactive• Aluminum, Tin, Lead

LANTHANIDES!!!• In a row below the

main part of the table• Top row, beneath

group 3• Soft, malleable,

shiny, high conductivity

• Mixed with other metals to make alloys

ACTINIDES METALS!!!• In a row below the main

part of the table• Bottom row

• Only actinium, thorium, protactinium, and uranium are found naturally. The rest are synthetic.

• Nuclei are unstable and break apart into smaller nuclei• Some last only a

fraction of a second!

SYNTHETIC!• Made in a nuclear reactor or a particle accelerator• Radioactive!
