found


principal quantum number - ✔✔RESOLUTION RESULT VERIFIED
ANSWERS✔✔->>n, divides an atom into shells n=1,2, 3.....


angular momentum quantum number - ✔✔RESOLUTION
RESULT VERIFIED ANSWERS✔✔->>l, divides each shell into
subshells s (l=0), p (l=1), d (l=2),f (l=3)


magnetic quantum number - ✔✔RESOLUTION RESULT VERIFIED
ANSWERS✔✔->>ml, divides each subshell into orbitals, 2l+1 shells in
each orbital, can be anywhere from
-l to +l


electron configuration - ✔✔RESOLUTION RESULT VERIFIED
ANSWERS✔✔->>shows the
distribution of electrons among the shells, subshells, and orbitals of an
atom


valence electrons - ✔✔RESOLUTION RESULT VERIFIED
ANSWERS✔✔->>electrons in the outermost shell

, core electrons - ✔✔RESOLUTION RESULT VERIFIED ANSWERS✔✔-
>>electrons in the inner shells paramagnetic - ✔✔RESOLUTION
RESULT VERIFIED ANSWERS✔✔->>contains unpaired electrons


diamagnetic - ✔✔RESOLUTION RESULT VERIFIED ANSWERS✔✔-
>>contains paired electrons


ionization energy - ✔✔RESOLUTION RESULT VERIFIED
ANSWERS✔✔->>amount of energy required to remove an electron
from an isolated, gas phase atom


electron affinity - ✔✔RESOLUTION RESULT VERIFIED
ANSWERS✔✔->>amount of energy released when a free, gas phase
atom gains an electron


crystal lattice - ✔✔RESOLUTION RESULT VERIFIED ANSWERS✔✔-
>>this forms when ionic compounds become solid; the ions are
stabilized by being surrounded by opposite charges. Also energy is
released.


octet rule - ✔✔RESOLUTION RESULT VERIFIED ANSWERS✔✔-
>>when atoms bond, they tend to
gain, lose, or share electrons to result in eight valence electrons
