Group 2 ­ The alkaline Earth metals

These Elements all have 2 valence electrons in
their outer shell which are lost when they bond
ionically in order to form 2+ ions, giving them full
outer shells.

Trends In Reactivity

· The thermal stability of carbonates changes down the group.
· Thermal decomposition is when a substance breaks down when heated.
· The amount of heat needed to decompose a group 2 element increases
causing the thermal stability to increase down the group.
· Group 2 carbonates decompose to form…
