Atom- The simplest particle of an element that retains all of the properties of that element
Atomic Number- The number of protons in an atom
Bond- Attachment
Chemical Reaction- The progress of breaking down bonds, forming new ones, or both
Compound- A pure substance that is made up of atoms of two or more elements
Covalent bond- a bond that is made up of atoms of two or more elements
Electron- A particle with a negative electric charge that orbits the nucleus of an atom
Element- A substance that ordinarily cannot be broken down chemically to form simpler kinds of matter
Energy level- a ring in an atom that holds electrons, the first ring holds at most 2 electrons, the second and third can each hold at most 8
Ionic bond- a bond formed my electrical attraction between two oppositely charged ions.
Mass- a fundamental property of an object generally regarded as equivalent to the amount of matter in the object
Matter- anything that occupies space and mass
Molecule- a chemical structure composed of one or more atom
Neutron- a particle in the nucleus of an atom with no electrical charge
Nucleus- in an atom, the core of protons and neutrons in an eukaryotic cell, the organelle that containing most of the DNA and directs most of the cell’s activities.
