6
Chemical bonds

• Nonmetals can form bonds with either metals or
  nonmetals.

7
Hydrogen

• Hydrogen is alone in the upper left corner of the
  periodic table because it is so different from
  the other elements.

8
Hydrogen

• Hydrogen is alone in the upper left corner of the
  periodic table because it is so different from
  the other elements.
• It contains only one proton and one electron (no
  neutrons)

  periodic table because it is so different from
  the other elements.
• It contains only one proton and one electron (no
  neutrons)
• Hydrogen makes up more than 90 of the atoms in

Metalloids

• They have some characteristics of metals and some
  of nonmetals.

12
Metalloids

• They have some characteristics of metals and some
  of nonmetals.
• The most common metalloid is silicon, which
  combines with oxygen to form sand, glass and
  cement.
