Number of protons Z = 30 Number of protons + neutrons A = 64 Number of neutrons N = 64 - 30 = 34 Since this is a nucleus there are no electrons There are 30 protons and 34 neutrons.

The atom is a complex system of particles. It's made up of a central nucleus consisting of protons and neutrons, called ...

The question of what protons or neutrons are made up of has an apparently simple answer: quarks and gluons. However, when it comes to atoms’ third component, electrons, the answer is not as easy.

Players read questions about energy levels and score points by picking the correct element as the answer. Electrons are in regions around the nucleus that are different distances away from the nucleus ...

For example, baryons, such as protons and neutrons, are combinations of three quarks bound tightly together by strong force-carrying gluons. When individual quarks are ripped from hadrons ...
