• ion charge +1
• low density, soft
• silver
• low melting point
• conductive
• reactive

• ion charge +2
• low density, hard
• solid at room temp

• very reactive

• not found alone in nature, too reactive
• instead found in compounds often with alkali metals
• toxic in elemental form
• bright colours as gases
• low boiling point
