Elements Quiz

 Element Families

1. Alkali Metals (Group 1)

Properties: Highly reactive, especially with water; soft; shiny.

Examples:

Lithium (Li)

Sodium (Na)

Potassium (K)

2. Alkaline Earth Metals (Group 2)

Properties: Reactive (less than alkali metals); usually found in compounds.

Examples:

Beryllium (Be)

Magnesium (Mg)

Calcium (Ca)

3. Transition Metals (Groups 3-12)

Properties: Good conductors of electricity and heat; malleable; often have multiple oxidation states.

Examples:

Iron (Fe)

Copper (Cu)

Gold (Au)

4. Post-Transition Metals

Properties: Softer, have lower melting points than transition metals.

Examples:

Aluminum (Al)

Tin (Sn)

Lead (Pb)

5. Inner Transition Metals

Properties: Include lanthanides and actinides, often radioactive.

Examples:

Lanthanum (La)

Uranium (U)

B. Non-Metals

1. Noble Gases (Group 18)

Properties: Colorless, odorless, non-reactive; full outer electron shells.

Examples:

Helium (He)

Neon (Ne)

Argon (Ar)

2. Halogens (Group 17)

Properties: Highly reactive non-metals; exist as diatomic molecules.

Examples:

Fluorine (F)

Chlorine (Cl)

Iodine (I)

C. Metalloids

Properties: Have properties of both metals and non-metals; semi-conductive.

Examples:

Boron (B)

Silicon (Si)

Arsenic (As)
