Periodic Table.Brittle

Can easily break or shatter

InsulatorsDoes not allow heat or electricity to pass through it

the Periodic Table.Metalloids share characteristics

with both metals and non-metalsSemi – conductors

The Periodic TableThe columns are called

groups or families.

Elements in the same group or family have similar properties.

The group number also determines the elements’ valence electrons.

The Periodic TableThe rows are called

periods.

The period determines how many energy levels an element has.

Group 1Group 1 is called the

Alkali Metals

These elements have 1 valence electron and are HIGHLY reactive.

Group 2Group 2 is called the

Alkaline Earth Metals

These elements have 2 valence electrons and are MODERATELY reactive.

Groups 3 – 12Groups 3 – 12 are called

the Transition Metals.

Group 13Group 13 is called the

Boron Group.

These elements have 3 valence electrons and are MODERATELY reactive.

Group 14Group 14 is called the

Carbon Group.

These elements have 4 valence electrons and are MODERATELY reactive.

Group 15Group 15 is called the

Nitrogen Group.

These elements have 5 valence electrons and are MODERATELY reactive.

Group 16Group 16 is called the

Oxygen Group.

These elements have 6 valence electrons and are MODERATELY reactive.

Group 17Group 17 is called the

Halogens.

These elements have 7 valence electrons and are HIGHLY reactive.

Group 18Group 18 is called the

Nobel Gases.

These elements have a FULL OUTER SHELL.

These are the most stable or LEAST reactive of all the elements.
