A function describing the location and wave-like behavior of an electron in an atom.
Exothermic reactions is where energy is released. Exothermic reactions are reactions that release energy into the environment in the form of heat. Exothermic reactions feel warm or hot or may even be explosive.
Whenever electrons are shared or transferred between atoms there is a chemical reaction.
The electrons that are being transferred between atoms (two or more) create new bonds, which enable the production of a new substance. This process is then known as a chemical reaction.
