front 1 Protons, Neutrons, and electrons | back 1 Subatomic Particles |
front 2 The nucleus | back 2 Almost all the mass of the atom Radius is 1/10,000 the size of the radius of the atom |
front 3 Atoms are electrically neutral because: | back 3 # of protons = # of electrons (e-) if electorally neutral |
front 4 Isotopes | back 4 Same #p, different #n They are the same element because same Z different masses because different #n |
front 5 Mass Number (A) | back 5 #p+#n=A z + n=A |
front 6 Ions | back 6 Charged particles formed when atom's gain or lose electrons |
front 7 Cation | back 7 Positively charged ion |
front 8 Anion | back 8 Negatively charged ion |
front 9 Atomic mass = | back 9 fraction of isotope * mass of isotope |
front 10 Artifical elements | back 10 Z > 92 |
front 11 Artificial elements do not have: | back 11 Atomic masses because thy have no naturally occurring isotopes |
front 12 Elements within the same row: | back 12 are in the same period |
front 13 Elements within the same column: | back 13 Similar chemical properties |
