A nucleon is a collective term for protons and neutrons inside an atomic nucleus, while the nucleus is the core of an atom, containing nucleons and thus most of the atom's mass.

The particles in the nucleus of an atom – protons and neutrons, collectively called nucleons – are held tightly together with extremely strong bonds. The forces in nuclear bonds are a million times stronger than those of electrons. Thanks to these bonds, our world is made of a rich variety...
you can change the number of electrons to make it a positively- or negatively-charged version of the same atom. A neutrally-charged atom will have the same amount of electrons as protons. Electrons exists in orbitals, which surround the nucleus of the atoms, and it is in these orbitals th...
5. Friction: It's the force that happens when two surfaces rub against each other, making it harder to move. 摩擦力:当两个物体表面相互摩擦时产生的力,使得移动变得更困难。 6. Electricity: It's the flow of tiny particles called electrons, which powers our devices and lights up our homes....
, electrons are elementary particles. This means they are not composed of even smaller particles. Also unlike protons and neutrons, electrons have essentially no mass. Finally, electrons are different from protons and neutrons in that they surround the nucleus instead of being part of the nucleus....
These are basic particles that do not help hold an atom’s nucleus together and are found in known matter. The electron and neutrino are examples of these particles. Quarks A quark is a basic particle that does not help hold an atom’s nucleus together. Quarks are extremely small, are cla...
