far apart with no order
physical properties
a quality or condition of a substance that can be observed or measured without changing the substance’s composition
chemical properties
the ability of a substance to undego a specific chemical change
examples of a physical property
hardness, color, conductivity, malleability
examples of a chemical property
burn, rust,rot, decompose, ferment, explode, corrode
compound
a substance that contains 2 or more elements which are chemically combined
element

nucleus components
neutrons and protons
nucleus’s charge

positive

protons make it positive

how to determine number of protons
look at the atomic number
how to determine number of electrons
look at the atomic number
how to determine number of neutrons
subtract the atomic number from the atomic mass
atomic number
the number of protons in an atom
atomic mass
the number of protons and neutrons in an atom
isotopes
atoms of the same element (because they have the same number of protons) but with different number of neutrons
notation for writing an isotope
atomic weight in superscript and atomic number in subscript to the left of the symbol
how to determine isotope abundance given average atomic mass
