have same # of valence electrons
similar chemical and physical properties
all of the above
forms same kind of ions
13
which two groups tend to bond often?
alkali metals with metalloids
nonmetals with nonmetals
Halogens and transition metals
halogens and alkali metals
14
What are metalloids?
a combo of metal and non- metal
non metals
metals
none of the above
15
alkali metals are different from transition metals because they..
are located on group 7
are soft as butter whereas transition metals are harder
Has 2 valence electrons
they are not as highly reactive as the transition metals are
16

alkaline earth metals and halogens
noble gases
only halogens
transition metals
