Now that you understand the element potassium, what could you tell me about its period and column? additionally because it is in that specific column, what properties does it have?

!

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:

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.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

what is the actual question though?
