Group 1 Alkali Metals

Identify the elements in Group 1 of the periodic table as the alkali metals.

Understand that alkali metals possess characteristic, predictable properties purely because they have a single solitary electron occupying their outer shell.

Describe the specific, observable reactions of the first three alkali metals with oxygen, chlorine gas, and liquid water.

Explain the clearly observable trend where the chemical reactivity of the elements actively increases when moving further down Group 1.

Explain how the explicit chemical properties and violent reactivity of the elements in Group 1 depend solely on the single outer shell electron of their atoms.

Predict the distinct properties and likely reactivity of heavier alkali metals based on clearly defined trends moving down the group.
