Group 2 elements- redox

• All have hydroxides which are alkaline- reflected in common name- alkaline earth metals

Hydroxide: A hydroxide is a compound of a metal with the hydroxide ion OH⁻ (as in many alkalis) or the group -OH.

Physical properties

• Reasonably high melting & boiling points
• Light metals with low densities
• Form colourless compounds

Electronic configuration

• Highest energy electrons in a s-sub shell
• 2 electrons more than the electronic configuration of nobel gas
• Outer shell containing 2 electrons

Reactivity of group 2 elements

• Reactive metals & strong reducing agents
• Oxidised in reactions- loses 2 electrons from outer s sub-shell- forms…
