Question

suppose you have a sample of potassium. describe several ways you could use periodic trends and a knowledge of valence electrons to predict the elements reactivity and how the element will behave in a chemical bond. potassium is inert because it is a noble gas. potassium is highly reactive due to its single valence electron. potassium is moderately reactive due to its two valence electrons. potassium is non - reactive because it has a full outer shell.

Explanation:

Potassium is an alkali - metal in Group 1 of the periodic table. It has one valence electron. Elements with one valence electron tend to lose that electron easily in chemical reactions to achieve a stable electron configuration, making them highly reactive. Noble gases have full outer shells and are inert. Potassium is not a noble gas. It has one, not two, valence electrons.

Answer:

Potassium is highly reactive due to its single valence electron.
