quantum energy level. Isotope- atoms of an element with identical chemical properties but with the different masses; isotopes are atoms of the same element with different numbers of neutrons. Ionic compound- chemical compound that are held together by ionic bonds; that is, bond of electrostatic attractions between negative and positive ions. Covalent bond- a chemical bond formed by sharing of a pair of electrons Covalent compound- chemical compound held together by a covalent bond or bonds. The

Level of Development and Level of Detail came into play with the advancement of computers and BIM technology. As the AEC industry began move towards using computer renditions for design and analysis, it became necessary to define the certainty with which drawings could be trusted. The detailing of elements changes throughout the duration of a project, so it is important for the team to be able to recognize what level of detail is provided and how trustworthy it is. For this reason, different levels

that creates matter combing all the different substances in the world. By the 1850’s 60 elements had been discovered with their chemical and physical properties. The First Periodic Table Dmitry Ivanovich Mendeleyev, a Russian chemist, in 1869 created a set of elements from lightest to heaviest, from hydrogen to uranium. Then he noticed similarities between the chemical properties of some of the elements and made groups that made columns. The he discovered that there is a missing element and discovered

have. The train must t-bone the bus. Hopefully this visual will help you to remember the condition required for a reaction to occur. Energy Diagrams: Energy diagrams are also called reaction progress diagrams as they depict the energy of the chemicals involved in the reaction through out the course of the reaction. The following is an example of an exothermic reaction: [pic] A catalyst will lower the activation energy of a reaction. The result is shown in the following reaction progress
