Nonmetals & Metalloids Worksheet
Write the letter of the correct answer on the line at the left.
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.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
