• Valence Electrons

• Electrons

Which of the following statements best explains why atoms bond?

• Atoms bond to form connections with other atoms

• Atoms bond to reach a full octet of valence electrons

• Atoms bond to make new substances

• Atoms bond to become less chemically stable

Which of the following best describes why the Noble Gases do not form bonds?

• Noble Gases are stable with 8 valence electrons

• Noble Gases have too many valence electrons

• Lose one electron and become a positive anion with a +1 charge

• Gain one electron and become a negative anion with a -1 charge

• Gain one electron and become a positive anion with a +1 charge
