What is the center of an atom called?Atoms:Atoms are the smallest indivisible working unit of matter. It is composed of three subatomic particles: neutrons, electrons, and protons. Neutrons are neutrally charged whereas electrons are negatively charged. Protons are the subatomic particles of an ...
The nucleus is orbited by the third type of subatomic particle, electrons. These subatomic particles are negatively charged and have very little mass in comparison to protons and neutrons. Electrons exist in an "electron cloud," which consists of the highly energetic orbits of these particles as ...
Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and neutrons. It is expressed in AMU ...
Today, atomic research is focused on studying the structure and the function of matter at the subatomic level. This not only consists of identifying all the subatomic particles that are thought to make up an atom, but investigating the forces that govern them. These include strong nuclear forces...

consists of identifying all the subatomic particles that are thought to make up an atom, but investigating the forces that govern them. These include strong nuclear forces, weak nuclear forces, electromagnetism and gravity. Here is a breakdown of all that we've come to learn about the atom so...
Any element listed on theperiodic tableconsists of specific atoms. Hydrogen, helium, oxygen, and uranium are examples of types of atoms. What AreNotAtoms? Some matter is either smaller or larger than anatom. Examples of chemical species that arenottypically considered atoms includes particles that...
An atom can be an ion, but not all ions are atoms. These are the important differences between an atom and an ion.
