Group 1

Explain the classification of elements into alkali metals (Group 1), halogens (Group 7), or noble gases (Group 0) based on their specific position in the periodic table.

Recall that alkali metals are characterized by being soft and having relatively low melting points.

Describe the vigorous reactions of lithium, sodium, and potassium with water.

Describe the reactivity pattern of lithium, sodium, and potassium with water, and use this trend to predict the reactivity of other Group 1 alkali metals.

Explain the observed reactivity pattern of Group 1 metals in terms of their respective electronic configurations.
