One may likewise ask, what atom has 20 neutrons?

one atom that chlorine-35 contains 18neutrons (17 proton + 18 neutrons = 35 corpuscle inthe nucleus) while an atom that chlorine-37 contains 20neutrons (17 protons + 20 neutrons = 37 corpuscle in thenucleus). Including or remove a neutron from an atom\"snucleus creates isotopes of a particular element.

What is the variety of neutrons the potassium?

Potassium-40 - It has actually 19 protons andatomic mass is 40. Hence, number that neutrons is 40 - 19which is 21. Potassium-41 - It has actually 19 protons andatomic mass is 41. Hence, number of neutrons is 41 - 19which is 22.

How numerous atoms space in potassium?


It is constantly constant. (e.g., H=1, K=19, Ur=92). For this reason ifyou look for potassium (symbol K in the regular table) youwill find that it has the atomic number of 19. This tells you thatpotassium has 19 protons and also - due to the fact that the number of protonsis the exact same as the number of electrons- additionally 19electrons.
