How many valence electrons does potassium have?

The only difference is the total number of shells they have. So, to answer the question again. Potassium (K) typically has 19 total electrons, 1 of which is in the outermost shell, and therefore 1 valence electron.

Does that help???

Perimeter? wheres the answers

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
