depends on isotope.

For the most common isotope of Potassium, Potassium-39 (93.08%):

  1. electrons = 19
  2. protons = 19
  3. neutrons = 20

How many protons and electrons are in present in a potassium atom?

A potassium atom has 19 protons and 19 electrons. The number of protons always equals the number of electrons in an atom, as they balance each other to maintain the atom's overall charge neutral.


A potassium atom has how many protons and electrons?

A potassium atom has 19 protons.An uncharged atom therefore has 19 electrons, but in solution many potassium atoms exist as ions (K+), with 18 electrons.
