atomic structures Flashcards
the number of p+ = to
the atomic #
the number of N = to
mass - atomic #
the number of e- is = to
the atomic # - charge
what does isotope notation look like
A (mass #)
N (atom/element)
Z (atomic #)
what are isotopes
they have the same number of protons (Atomic #) but different number of neutrons and mass number
Sub shell/sub energy levels
sub shells within main shells.
depending on the energy level, it will have the number of sub shells there. Like N=1, has 1 sub shell, but N=4 has 4.
the further away you want your electrons…
the more energy it takes. Electrons in the outermost energy levels are the ones with highest energy because it takes more effort and energy to pull electrons away from the center.
N=1 can hold __ e-
N=2 can hold __ e-
N-=3 can hold __e-
N-=34 can hold__e-
