1. (a) How many electrons are in a neutrally charged potassium atom?

(B) How many electron are in a +1 charged potassium atom?

(C) How many electrons are in a -2 charged sulfur atom?

Answer 1

A) Neutral Potassium Atom - 19 electrons  (its the atomic number)

B) +1 Charged Potassium Atom - 18 electrons (its the atomic number minus 1 because electrons are negative and it has a positive charge)

C) -2 Charged Sulfur Atom - 18 electrons (its the atomic number plus 2 because it has more negatives than positives, more electrons than protons)
