The scientific method is nothing more than a process for discovering answers. While the name refers to “science,” this method of problem solving can be used for any type of problem. Teaching Tip: Ask kids to provide an example of identifying a problem in their life and how they solved it. For this assignment, I [...]
Covalent Bonds
February 5, 2011 By
A bond is an attraction between atoms. A covalent bond results from the sharing of valence electrons between two atoms. Each covalent bond is made up of one pair of electrons. Both electrons in the bonding pair can be from one atom, or the pair can contain one electron from each atom. When atoms covalently [...]
What Are Hydrogen Bonds?
January 29, 2011 By
YIKES! While they sound very similar, don’t confuse the term ” a hydrogen bond” with the term “a hydrogen bomb”! Since a hydrogen bond forms between molecules with polar covalent bonds, I will first explain polar covalent bonds. covalent bond: Formed between two atoms that share valence electrons (electrons in the outermost energy shell). The [...]
Covalent Bonds

Chemical bonds are simply how the atoms “hook” together. Instead of atoms being physically attachment, much like a button that hooks into a button hole, chemical bonds are electrical attractions, called electromagnetic forces. Electrons are negatively charged particles that move around the center of an atom called the nucleus. The nucleus is where the atom’s [...]
Chemistry: Reducing Agent
January 26, 2011 By
In a chemical redox reaction, the reducing agent donates electrons to another element. Thus, a reducing agent is an element that causes another element to be reduced (to gain electrons). When a reducing agent loses its electrons, it is said to be oxidized. In a redox reaction, there has to be one element that loses [...]
Chemistry:Oxidizing Agent
January 26, 2011 By
An oxidizing agent is a substance that causes another substance to be oxidized (to lose electrons). In the diagram, oxygen is the oxidizing agent because it draws away magnesium’s valence electrons.An oxidizing agents cause other elements to lose electrons. The oxidizing agent gains the electrons lost by other elements. While oxygen is the oxidizing agent [...]
Chemistry: Redox
January 26, 2011 By
Oxidation is a type of chemical reaction in which electrons are transferred from one substance to another. For oxidation to occur, one substance must lose electrons and a second substance must gain the lost electrons. The substance gaining electrons is said to be reduced and the substance losing the electrons is said to be oxidized. [...]
Aerobic Oxidation
January 26, 2011 By
Oxidation is a chemical reaction in which electrons are transferred from one substance to another. Aerobic Oxidation is a chemical reaction in which one substance combines with oxygen. Like any oxidation reaction, there is a transfer of electrons. When free oxygen is part of the reaction, electrons are transferred from one substance to oxygen. The [...]
Chemical Reaction
January 25, 2011 By
A chemical reaction is the changing of one or more chemicals into one or more different chemicals. Reactants : The name for the starting chemicals of a chemical reaction. Products: The name for the resulting chemicals of a chemical reaction. The model for a chemical reaction equation is: reactants————-> products Types of Chemical Reactions 1. [...]
