Unformatted text preview: C hemical behavior of an atom depends mostly on its valence electrons. Atoms with the same number of valence electrons exhibit similar chemical behavior. 7. Explain why weak bonds are important to living organisms. Weak bonds are advantageous because the contact between molecules can be brief. They reinforce the shapes of large molecules and help molecules to adhere to each other. The ionic bond, which is relatively weak in the presence of water, is specifically important in living organisms as is the hydrogen bond....
