Element Properties

These elements are highly reactive in water and have one valence electron.

• Alkali metals

• Alkaline earth metals

• Halogens

• Noble gases

1. These elements are not shiny, ductile, or malleable

• Transition metals

• Metalloids

• Post-transition metals

• Nonmetals

These elements are radioactive and decay into other elements over time. They are soft, ductile metals that have a high density.

• Alkali metals

• Alkaline earth metals

• Actinides

• Nonmetals

NGSS.HS-PS1-8

These elements look like metals, but act like nonmetals.

• Lanthanides

• Metalloids

• Actinides

• Noble gases

These elements are unreactive due to their 8 valence electrons.

• Lanthanides

• Metalloids

• Actinides

• Noble gases

1. These elements are highly reactive nonmetals that are diatomic and tend to form salts.

• Lanthanides

• Metalloids

• Halogens

• Noble gases

1. These elements are solid at room temperature, but are not great conductors due to their low melting points.

• Lanthanides

• Metalloids

• Post-transition metals

• Noble gases
