Neutrons are also present in the nucleus with the protons, but do not have any charge. Potassium-39 and potassium-40 are isotopes of each other. We know that the mass of an atom is equal to the sum of number of protons and number of neutrons. So there are 19 protons and 19 electrons.

Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. A neutral atom has the same number of protons and electrons (charges cancel each other out).

Atomic Number – Protons, Electrons and Neutrons in Potassium. Potassium is a chemical element with atomic number 19 which means there are 19 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.

Kids learn about the element potassium and its chemistry including atomic Potassium atoms have 19 electrons and 19 protons with one valence electron in the There are three isotopes of potassium that occur naturally: K-39, 40, and

The Periodic Table tells us that potassium has an Atomic Mass of ≈39. So there are 39 - 19 = 20 neutrons. Protons and electrons can be combined into neutrons. Atom structures and identifying protons, neutrons, and electrons in an atom.

Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons.
