Question

Potassium is a highly reactive element.
True
False

Answer 1

tr00

Answer 2

This is true, but why? Well, potassium is found in group 1A (Group 1 by the new system) of the periodic table, which means that it has only one valence electron. Like all elements, potassium wants to have its electron configuration resemble that of the nearest noble gas (so that it becomes stable!) so it would really, REALLY like to give that one electron away.

It is a very reactive element because it can let go of its electron very easily, and we all know electrons are the main reason for chemical reactions :)
