have similar properties. The periodic table is arranged by periods and groups. The atomic number usually increases when moving across a row or period. The atomic structure of an atom consists of an electron, a proton, and a neutron. Electrons have light particles and a negative charge. Protons have heavier particles and have a positive charge. Neutrons also have heavier particles but do not a charge thus being neutral. Elements are commonly classified ad metals, nonmetals, or metalloids. The trend

* What does that mean? * Theory: Explanation * Atomic: Of atoms * How did we develop this theory? * Began with the Greeks * Democritus- 470-380 B.C. * Matter cannot be broken down indefinitely. At some point you end up with a piece that cannot be divided. That smallest piece he called an atom, from the Greek word atomos, which means “indivisible” * All matter is composed of atoms, which are bits of matter too small to be seen. These atoms

center core of the atom. There are two parts of a nucleus and they consist of protons and neutrons. Protons contain a positive charge and neutrons contain no charge at all. Atoms of the same element have the same number of protons. The remainder of the atom is made up of an electron field. Electrons are negatively charged particles and they whirl around the nucleus at a great speed. The number of electrons and protons are equal. 2) Describe metallic bonding. Metallic atoms have only a few

definition defines acids as substances which increase the concentration of hydrogen ions (H+), or more accurately, hydronium ions (H3O+), when dissolved in water. The Brønsted-Lowry definition is an expansion: an acid is a substance which can act as a proton donor. By this definition, any compound which can easily be deprotonated can be considered an acid. Examples include alcohols and amines which contain O-H or N-H fragments. A Lewis acid is a substance that can accept a pair of electrons to form a covalent
