How many protons electrons and neutrons are in an atom with an atomic number of seventy nine and an atomic mass of one hundred ninety seven?

Answer 1

59 = # of protons and # of electons

59 protons make up 59 of the mass number (electons have an insignificant mass), so the rest of the mass must be from neutrons:

96 - 59 = 37 neutrons

Answer 2

79 protons, 79 electrons and 100 neutrons.

Answer 3

The number of protons is the same as atomic number. So, if atomic number is 19, the number of protons is 19. This is Potassium, i believe.

Answer 4

The number of neutrons is always equal to the difference between the atomic number and the mass number; in this instance, 96 - 42 = 54.

Answer 5

There are 79 protons (same as the atomic number), 118 neutrons (Atomic Mass minus atomic number), and 79 electrons (same as the number of protons in a neutral atom).

Answer 6

One proton and one electron. No neutrons.
