electrona negatively charged subatomic particle that is found in the space outside the nucleus of an atom

atomic numbera unique number for each element that equals the number of protons in an atom of that element
mass numberthe sum of the number of protons and neutrons in the nucleus of an atom
isotopesatoms of a given element that have different numbers of neutrons and different mass numbers
energy levelsthe possible energies that electrons in an atom can have
electron cloudvisual model of the most likely locations for the electrons in an atom
orbitala region of space around the nucleus where an electron is likely to be found
