Elements are organized in the periodic table according to increasing atomic number.

Atomic number is the number of electrons in an atom of an element. 

Elements in the periodic table are grouped as either metals or metalloids.

Place a        beside each statement that is true and an         beside each statement that is false.

Classify each element as a metal, metalloid, or non­metal.

Silicon is in computer chips.

Copper is in pennies.

Carbon is in all organisms.

metalloid metal

Look for sodium and potassium in the periodic table. Compare and contrast sodium and potassium.
