Who found that the atomic number was equal to the number of protons in the nucleus...
Which of these statements is true? The number of electrons outside the nucleus is the same as the number of neutrons in the nucleus. The mass number of an atom is the number of protons plus the number of neutrons. The atomic number of an atom is the number of valence electrons outside the nucleus. In an ion, the number of electrons must be equal to the number of protons.
The atomic number is equal to the number of _______ in the nucleus of each atom of an element.

The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six protons and six neutrons, while a nitrogen-14 nucleus comprises seven protons and seven neutrons. You perform a nuclear physics experiment in which you bombard nitrogen-14 nuclei with very high speed carbon-12 nuclei emerging from a particle accelerator. As a result of each such collision, the two nuclei disintegrate completely and a mix of different particles are emitted, including electrons, protons,...
In small atoms, the number of neutrons and protons in the nucleus tend to be equal. As you move to the larger atoms, you tend to see more neutrons than protons. This is because more neutrons means more strong nuclear force without adding electrostatic forces the neutrons are needed to increase the gravitational interactions in the nucleus the neutrons are necessary for repelling the electrons from the nucleus
The atomic nucleus is most often made up of O electrons O protons and neutrons O neutrons O Fermions O protons
