Potassium occurs naturally on earth in three isotopes with mass numbers 39, 40, and 41. Of these, the isotope K-40 is known to be radioactive, but has a very long half life. There are many other radioactive isotopes of potassium.
The element with one more proton than argon is potassium, which has atomic number 19. Argon has an atomic number of 18.
The mass number of Am-241 is 241; each isotope has another mass number.
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
the mass number of sodium is 23
