Group 1

Recall the simple physical and chemical properties associated with Group 1 elements.

Explain how the chemical properties of Group 1 elements are dictated by the presence of a single electron in their outer shell.

Identify Group 1 elements as the alkali metals and describe them as soft metals with low density.

Describe the reaction of Group 1 metals with non-metals, such as chlorine and oxygen, to form highly soluble, colorless ionic compounds.

Explain the vigorous reactions between alkali metals and water, noting the formation of metal hydroxides that produce alkaline solutions.

Predict properties from given trends, specifically recalling that the reactivity of alkali metals increases as you move further down Group 1.
