States of matter solids

States of matter; solids

Metals vs. nonmetals


Which elements are metals

Which elements are metals?

Metals are on the left side of the periodic table


Properties of metals

Solids at room temp. exceptMercury

Shiny “metallic”

High Density

Properties of METALS

Malleable

Ductile

Conductor of electricity

Conductor of heat


Periodic table

Periodic Table

All the elements shaded in yellow have those metallic properties.


Some common uses of metals are

Some common uses of metals are

in sprinkler-systems. (Bismuth)

in roadflares; the red color. (Strontium)

in medicine; absorbs harmful x-rays & gamma rays (Barium)


Periodic table1

Periodic Table

The elements in Group 1 are the absolute best of all metals!

They are called ALKALIMETALS


Which elements are nonmetals

Which elements are NONMETALS?

Nonmetals are on the right side of the periodic table


Properties of nonmetals

Mostly gases at room temp.

Dull; not shiny

Low Density

Properties of NONMETALS

Brittle; not malleable

Non- conductors


Periodic table2

Periodic Table

All the elements shaded in blue have those nonmetallic properties.


Some common uses of nonmetals are

Some common uses of nonmetals are

in dandruffshampoos (Selenium)

in toothpaste (Fluorine)

in rayon (Sulfur)


Periodic table3

Periodic Table

The elements in Group17 are the absolute best of all nonmetals!

(or the worst of all metals!)

Group 17 elements are called HALOGENS


What about the green elements

What about the green elements?

These are called METALLOIDS.


Properties of metalloids

They are the transition elements between metals and nonmetals

Some are shiny (aluminum)

Some are dull (arsenic)

Properties of METALLOIDS

Most are considered semi-conductors


Some common uses of metalloids are

Some common uses of metalloids are

in aerospace (strong but light) (Boron)

in infrareddetectors (Germanium)

in ratpoisoning (Arsenic)


Pick one element that interests you metal or nonmetal

Periodic Table

periodic table

Pick one element that interests you; metal or nonmetal!

You are going to adopt an element and we will do a research project
