A. A working definition of matter is that it takes up space, has mass, and has measurable properties. Matter is comprised of atomic, subatomic, and elementary particles.
B. Electrons are key to defining chemical and some physical properties, reactivity, and molecular structures. Repeating (periodic) patterns of physical and chemical properties occur among elements that define groups of elements with similar properties. The periodic table displays the repeating patterns, which are related to the atom's outermost electrons. Atoms bond with each other to form compounds.
C. In a chemical reaction, one or more reactants are transformed into one or more new products. Many factors shape the nature of products and the rates of reaction.
D. Carbon-based compounds are building-blocks of known life forms on earth and numerous useful natural and synthetic products.

Tutorial
This tutorial will help the learners to understand the molecular structure of the water molecule, its inter- and intra-molecular bonds, and the formation of hydroxide ions.
Type: Tutorial
Video/Audio/Animation
- Differentiate between electron pair and molecular geometry
- Learn how to name electron pair and molecular geometries for molecules with up to six electron groups around the central atom
- Illustrate how electron pair repulsion affects bond angles
Type: Video/Audio/Animation
Virtual Manipulative
In this simulation, explore the interactions between various combinations of two atoms. Specific features of the simulation allows you to see either the total force acting on the atoms or the individual attractive and repulsive forces.
Options for learning:
- Explain how attractive and repulsive forces govern the interaction between atoms.
- Describe the effect of potential well depth on atomic interactions.
- Describe the process of bonding between atoms in terms of energy.
