Problem: Ionic, covalent, and metallic bonds. The three different substances shown here are held together by different types of chemical bonds.If the white powder were sugar, C12H22O11, how would we have to change this picture?

FREE Expert Solution

In this problem, we are asked what we would change in the given figure if the white powder were sugar, C12H22O11.


Recall that:

  • Ionic bonds are held together due to the attraction between the oppositely charged ions, there is a transfer of electrons.
    • Bond forms between metals and nonmetals
  • Covalent bonds are bonds form by the sharing of electrons.
    • Typically, between two nonmetals
  • Metallic bond forms between positively charged atoms in which the free electrons are shared among a lattice of cations
    • Bonds between two metals


To solve this problem, we need to look at the individual elements that made up the compound.

Problem Details
Ionic, covalent, and metallic bonds. The three different substances shown here are held together by different types of chemical bonds.

If the white powder were sugar, C12H22O11, how would we have to change this picture?

A photograph shows a spoon holding a powdered substance over a glass of water. The spoon is comprised of metallic bonds, with atoms held together by a “sea of electrons” surrounding the nuclei; a diagram shows identical atoms arranged in a regular structure.  The powder is comprised of ionic bonds, with ions held together by local electrostatic attractions; a diagram shows alternating positive and negative ions arranged in a regular structure.  The water molecules are comprised of covalent bonds, with atoms held together by sharing electrons in localized bonds; a diagram shows an oxygen atom single bonded above, angled left and right, to two hydrogens.
