Unit 3 Metals, Nonmetals, & Metalloids

Metals & Reactivity

The metals on the far left are the most reactive because they have the fewest valence electrons

Bond easily

Properties of Metals

Luster

Good conductor

Mailable

Ductile

High melting point

Solid

Chemical properties of metals

Non-combustible

Oxidize/rust

Nonmetals & Reactivity

The most reactive nonmetal is Florine

As you move up and right, reactivity increases until the noble gases

Noble gases are non-reactive

All their electron shells are full

Properties of Nonmetals

Brittle

Bad conductors

Dull

Low melting & boiling point

Chemical properties of nonmetals

Are acidic or neutral

Acidic nonmetals combine with metals to form salts

Physical properties of metalloids

Not as brittle as nonmetals

Some luster

Hard

Semi conductors

Chemical properties of metalloids

More like nonmetals

Not very reactive
