Based on hardness, shininess, malleability, and ductility
wide range of chemical properties
in a group with those who have similar properties
high melting point (solid at room temperature)
Conductors of heat
1, 2, 3 valence electrons
when metals lose an ion it becomes
how many nonmetals are there
do non metals have high density?
no, they have low density
poor conductors of heat
why do nonmetals have low boiling points?
most are gases
these have some characteristics of metals and nonmetals
valence electrons for metalloids are
