Terms in this set (12)
atoms tend to lose or gain electrons to
create a filled outermost shell
which atoms will tend to lose electrons
which atoms tend to gain electrons
what is the charge for ions in group 1
what is the charge for ions in group 17
why don't the noble gases of group 18 form ions?
cause their valence shells are already filled to capacity
where on the periodic table is the attraction between an atoms nucleus and its valence electrons the weakest?
the elements on the left
where on the periodic table is the attraction between an atoms nucleus and its valence electrons the strongest?
the elements on the right
why is the valence electron of groups 1 easily lost?
cause its not held very tightly
why do the ions of group 17 pull in an extra electron?
They are on the right side and the attraction is very strong
for which groups does the shell model work for ion formation?
for which group does the shell model not work well?
