Use complete sentences to answer the following questions.
19. Lithium is a metal and hydrogen is a nonmetal. Explain why both are placed in Group 1.
They both have 1 valence electron.
20. Explain the difference between malleable and ductile.
Malleable means you can pound the substance into sheets; ductile means you can draw the
substance into wire. These traits are typically found amongst metals.
21. Why are the noble gases so stable?
Noble gases are so stable because they have a full outer energy level, which is called an octet.
Atoms gain, lose or share electrons to achieve an octet, noble gases already have one so most of them do
not readily react with other elements.
