Web2 mrt. 2024 · The element potassium has 19 protons and 20 neutrons, for a total mass number of 39. What is the symbol for potassium The symbol for potassium is K. Where is potassium on the periodic table Potassium is located on the periodic table in the first column on the left side. It is classified as an alkali metal. WebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8.
