Document Summary
Matter: anything that contains mass and occupies space; all life forms are compose of this; three states: solid, liquid, gas. Atoms: smallest functional units of matter that form all chemical substance and ultimately all organisms; they cannot be further broken down into other substances by ordinary chemical or physical means; all matter is composed of atoms. Element: a pure substance of only one kind of atoms. Atomic nucleus: center of an atom where protons and neutrons are confined in a small volume. Ions: atoms that have gained or lost one or more electrons. Ernest rutherford: most of the volume of an atom is empty space. Electrons move extremely fast, thus it is difficult to precisely predict exact location. Orbitals: the region of space surrounding the nucleus in which there is a high probability of finding an electron. Energy: the capacity to work or effect a charge. Kinetic energy: energy of moving matter; electrons orbiting a nucleus have this.
