QuestionAnswer
the ability to attract electrons from nearby atoms electronegativity
this number tells you the number of valence electrons group number
ions that have a positive charge + lose valence electrons cation
groups that are anions 5A, 6A, 7A
what is the rule about d block electron configurations period minus 1
said that electrons are placed in the lowest energy level first (s) Aufbau
ions that have a negative charge + gain valence electrons anions
groups that are cations 1A, 2A, 3A
said that electrons will have the same spin until each orbital has 1 electron Hund
element that is stable with only 2 valence electrons He
a visual representation of only the valence electrons Lewis Dot structure
element where the 3 electron configurations stop working V
element(s) that are the first exceptions to the electron configuration rules Cr and Cu
