Basics of Atom
... But structurally, we can think of an atom like a tiny solar system. In the center of the atom is the nucleus which is a cluster of protons and neutrons Thus an atom consists of three main parts: protons, neutrons, and electrons. These parts are known as subatomic particles or fundamental particles. ...

Periodic Properties of the Elements Effective Nuclear Charge, Zeff
... Atomic radii decrease along a row. Why? Zeff increases as we add electrons to the same energy level. The increase in nuclear charge as we move across a row is not completely screened by the additional valence electrons so Zeff becomes larger for each valence electron. (Atomic radii of transition met ...
