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.

Answer:
Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.
