Physical Science 1

A stack we had to create for a homework assignment.

TermDefinition
Model A representation of something in any form.
Atom The basic building block of the entire universe.
Nucleus The center of something, in this case an atom.
Proton A subatomic particle with a positive charge.
Neutron A subatomic particle with a neutral charge.
Electron A subatomic particle with a negative charge.
Atomic Number The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
Atomic Symbol The atomic number of an element determines its position in the Periodic Table.
Subatomic Particle A particle/entity smaller than a atom.
Molecule A combination of two or more atoms.
Lewis Structures Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
Bohr Model A simple definition of Bohr's atomic model is: electrons orbit the nucleus at set distances.
Electron Shell The electrons in the outermost occupied shell (or shells) determine the chemical properties of the atom; it is called the valence shell.
Valence Electron A valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond.
Matter The state of an object. It can be either liquid, gas, or solid.
