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.


How many protons neutrons and electrons are in k39?

In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).


How many protons and neutrons are there in a potassium's atom?

There are: 19 protons 20 neutrons and a total of 19 electrons (2 being in the first energy level, 8 being in the second and third, and 1 being in the last, or fourth, energy level) in a Potassium(K) atom.


What is an atom compromise of?

Three basic parts of an atom?

Protons, neutrons, and electrons are the three basic parts of an atom. Protons have a positive charge, neutrons carry no charge, and electrons have a negative charge and orbit around the nucleus of an atom.


How many protons electrons and neutrons in the element potassium?

The atomic number of potassium is 19. So there are 19 protons and 19 electrons. The number of neutrons depends on the isotope. The most stable isotope of potassium (K-39) has 20 neutrons (39 - 19 = 20).


How many electrons and protons are there in potassium?

A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.

What atoms are in potassium?

Which potassium atom do you want? At what level do you want to count particles?potassium-38: either 19 protons & 19 neutrons or else 114 quarkspotassium-39: either 19 protons & 20 neutrons or else 117 quarkspotassium-40: either 19 protons & 21 neutrons or else 120 quarkspotassium-41: either 19 protons & 22 neutrons or else 123 quarkspotassium-42: either 19 protons & 23 neutrons or else 126 quarkspotassium-43: either 19 protons & 24 neutrons or else 129 quarkspotassium-44: either 19 protons & 25 neutrons or else 132 quarksI hope you did did not mean to count either the mesons or gluon that's convey the strong force in each case.
