1. Which of the following is NOT a

property of most nonmetals?

A found on the right side of the

periodic table

B solids tend to be dull and brittle

C excellent electric conductivity

D many are gases at room temperature

3. Two of the same atoms bonded

together is called a(n)

A isotope

B diatomic molecule

C binary atom

D semiconductor

2. The only nonmetal in Group 14 is

A carbon

B oxygen

C nitrogen

D fluorine

4. The highly reactive nonmetals of

Group 17 are called the

A noble gases

B metalloids

C halogens

D actinides

If the statement is true, write true. If the statement is false, change the underlined word

or words to make the statement true.

5. Atoms of nonmetals usually lose electrons when they combine

with other atoms.

6. When two or more atoms bond by sharing electrons, they form

a molecule.

7. The elements that have some properties of metals and some

properties of nonmetals are called halogens.

8. Helium has chemical properties so different from those of the

other elements that it cannot be placed in any group.

9. Substances that can carry electric current under some

conditions but not under others are called semiconductors.

10. The Group 15 element oxygen is used to make compounds

known as fertilizers.
