What type of elements form covalent bonds?

  • Covalent bonds often occur between

nonmetals.

  • In a covalent bond, both atoms attract the

shared electrons at the same time.

Practice forming covalent bonds

  • Choose any two elements that will

form a covalent bond

  • Drag each element above the line
  • Place them in the order they would

appear in a chemical formula

  • Ungroup each element to move the symbol and

electrons

  • Return elements to the original

configuration and regroup
