Ions are formed when an atom either loses or gains electrons. The number in thesuperscriptwill tell you the magnitude of this change. Say you have Cl-. How many electron, protons and neutrons does this ion have? The process for finding these values is very similar to what was done above...
Electrons Can Behave as Waves: The Quantum Model of the Atom - "Atoms are in your body, the chair you are sitting in, your desk and even in the air. Learn about the particles that make the universe possible."
As you probably know, electrons are the minute charged particles that occupy the outer regions of atoms. (They're also the particles that carry electricity around circuits.) In an electron microscope, a stream of electrons takes the place of a beam of light. An electron has an equivalent ...
Atoms share electrons to create chemical bonds. Understanding the nature of this bonding begins by knowing the number of electrons associated with each atom. With the information from a periodic table, and some straightforward arithmetic, you can calcula
