Which is the most accurate description of potassium (k)? a. it is a metalloid. b. it is dull, brittle, and a poor conductor of electricity. c. it will tend to gain an electron in a chemical reaction. d. it will tend to lose an electron in a chemical reaction.

Option (D) is the correct answer.

Explanation:

Atomic number of potassium is 19 and its electronic distribution is 2, 8, 8, 1. Since, it contains only 1 valence electron therefore, it belongs to group 1 of the periodic table.

And, elements of group 1 are also known as alkali metals. Hence, potassium being a metal will readily lose its valence electron in order to gain stability in a chemical reaction.

And, being a metal potassium will be good conductor of heat and electricity, malleable and ductile etc.

Therefore, we can conclude that the statement it will tend to lose an electron in a chemical reaction is the most accurate description of potassium (K).
