1. Dalton's idea that atoms cannot be divided into smaller parts was disproved by the discovery of the _______. (electrons?)
2.The description of the structure of the atom is called the _______. (atomic model)
3. In a water molecule, two atoms of hydrogen and one atom of oxygen share electrons. A _____ bond is found in a water molecule. (convalent)
4. Sodium chloride is formed when the metal sodium bonds to the nonmetal chlorine. The atoms are held together by a(n) ______. (ionic bond)
5. One way the modern atomic model differs from Thompson's atomic model is that electrons are no longer scattered throughout an atom's positive matter like chocolate chips in cookie dough. Instead, each electron is outside of the nucleus occupying a specific ____. (energy level, orbital, or shell)
