4.78 grams K (1 mole K/39.10 grams)(6.022 X 1023/1 mole K)(19 protons/1 atom K)
= 1.40 X 1024 protons in that mass potassium

How many protons are in one atom of potassium (K)?
19
How many protons does k-40 have?
The atomic number of potassium is 19. So there are 19 protons, 19 electrons. In K-40 isotope, there are 21 neutrons.
How many protons and electrons does K have?
19 electrons, 19 protons and 20 neutrons
How many protons neutrons and electrons are in k40?
K always has 19 protons, because that is what defines it as an element.40, the atomic mass is the sum of protons and neutrons. So if you subtract the number of protons from the atomic mass, you get the number of neutrons.40-19=21 neutrons
What does K 19 and 39.098 represent on a periodic table?
K is the symbol for potassium. 19 is the number of protons and 39.098 is the mass number (Protons + Neutrons + Electrons).
How many protons and electrons does K?
An electric-neutral K atom has 19 protons and 19 electrons.
How many neutrons and protons does K-40 have?
it has 21 neutrons and 19 protons
