There are several subatomic particles. In general the term refers to the three main parts of an atom - the proton, the neutron, and the electron. But the proton and neutron are made up of even smaller particles called quarks (there are 6 of those!) and then there are all sorts of gluons and mesons... but I think the basic answer is the one that you want. Stick with proton, electron, and neutron.
Helium nucleus.
The particles in an atom are the protons, the neutrons, and the electrons.
The energy of an object or particle due to its location relative to another object or particle is called gravitational potential energy. This energy is determined by the mass of the objects, the distance between them, and the gravitational constant. It represents the potential for work to be done as a result of the gravitational force between the objects.
The term "God Particle" was popularized by physicist Leon Lederman in his book "The God Particle: If the Universe Is the Answer, What Is the Question?" However, Lederman originally wanted to refer to the Higgs boson as the "Goddamn Particle" due to its elusive nature, but the publisher suggested "God Particle" for marketing reasons.
Particles with opposite electric charges will attract one another. For example, a positively charged particle will attract a negatively charged particle. This is known as the principle of electric attraction.
