A negative ion is called an anion, pronounced as if Ann were an ion. A positive ion, whether it is a single atom or a group of atoms all with the same charge, is called a cation, pronounced as if a cat were an ion. An ionic compound is a group of atoms attached by an ionic bond that is a major unifying portion of the compound. Any positive ion will bond with any negative ion. The attraction between a positive ion and a negative ion is an ionic bond. When the number of electrons exceeds the number of protons, the ion is negative. The non-metal ions tend to gain electrons to fill out the outer shell. Non-metal ions and most of the polyatomic ions have a negative charge. When an atom loses electrons it becomes a positive ion because the number of protons exceeds the number of electrons. The negative charge of the electrons can be offset by the positive charge of the protons, but the number of protons does not change in a chemical reaction. Some atoms, such as metals tend to lose electrons to make the outside ring or rings of electrons more stable and other atoms tend to gain electrons to complete the outside ring. The Law of Constant Proportions states that a given compound always contains the same proportion by weight of the same elements. A molecule is a single formula of a compound joined by covalent bonds. The word formula is also used to mean the smallest bit of any compound. It might have the right elements in it to be water, but it does not have them in the right proportion.

H 2O 2 is the formula for hydrogen peroxide. Hydrogen sulfide does not have the same types of atoms as water. This formula indicates that there are two hydrogen atoms and one oxygen atom in the compound. If any other elements are attached, it is not water.

Each hydrogen atom is attached to an oxygen atom by a bond. One oxygen atom and two hydrogen atoms make up water. Exactly the same elements in exactly the same proportions are in every bit of the compound. Every bit of that material is exactly the same. In chemical reactions the elements do not change from one element to another, but are only rearranged in their attachments.ДЄ compound is a group of atoms with an exact number and type of atoms in it arranged in a specific way. If we study the changes brought about by moving protons or neutrons, we would be studying nuclear physics. Since chemistry is the study of elements, compounds, and how they change, it might be said that chemistry is the study of electrons. There are bonds that come about from partial charges or the position or shape of electrons about an atom.

There are bonds that occur due to a full electrical charge difference attraction. There are bonds that occur due to sharing electrons. Atoms may be held together for any of several reasons, but all bonds have to do with the electrons, particularly the outside electrons, of atoms.
