Answer:

Here's what I get  

Explanation:

Potassium is in Group 1 and Period 4 of the Periodic Table.

Group 1 elements are called alkali metals.

In general, alkali metals have the following physical properties:

  • Silvery white
  • Soft enough to cut with a knife
  • Relatively low melting points
  • Good conductors of heat and electricity.

Their most obvious chemical properties are that they are highly reactive.

They react with atmospheric oxygen to form a dull coating of the metal oxide.

They all react with water to form hydrogen and a basic metal hydroxide.

The reaction of potassium with water (below) is quite vigorous.
