This is not a math question.
This is a science question: please explain the difference between protons, nucleus, and neutrons.
I am confused about these things. Help.
The atom is visualized as having spinning electrons around the nucleus of the atom. The nucleus contains protons (the same number as the number of electrons unless the atom is an ION) . Protons determine the atomic number of the element. The nucleus also contains a variable number of neutrons (thus creating isotopes).
Atoms are mainly composed of protons, neutrons, electrons, and sometimes morons. Atoms that have morons and have extra neutrons are isotopes of morons and have higher density.
Generally, if more than a 10% of the atoms in your body have morons then you belong in one or more classes of morons. Those who have isotopes of morons belong in the groups of dense morons.
