Draw the Lewis structures of the two atoms in the compound. 2. Indicate whether the element is a metal, metalloid or a nonmetal. 3. Indicate how many electrons the atoms wants to gain and how many it wants to lose. 4. Show the transfer of electrons and write down the ion that is formed after the transfer of electrons. 5. Write the completed formula.and the name of the compound.</p><p>COMPOUND: NaCl</p><p>Metal Metalloid Nonmetal Metal Metalloid Nonmetal</p><p>Na: Cl:</p><p>Gain: ______electrons Gain: ______electrons</p><p>Lose: ______electrons Lose: ______electrons</p><p>Ion formed Na: Cl: Chemical Name of the Formula Compound</p><p>COMPOUND: Rb2O</p><p>Metal Metalloid Nonmetal Metal Metalloid Nonmetal</p><p>Rb: O:</p><p>Gain: ______electrons Gain: ______electrons</p><p>Lose: ______electrons Lose: ______electrons</p><p>Ion formed Rb: O: </p><p>Chemical Name of the Formula Compound</p><p>DISCUSSION QUESTIONS 1. What happens with the electrons when metals and nonmetals bond?</p><p>2. What do metals such a Mg, Ca, and Na tend to do with electrons? Explain why.</p><p>3. What do nonmetals such as F, Cl, and O tend to do with electrons. Explain why.</p><p>4. Why are noble gases such as Ar and Kr not involved in bonding? 5. What is the charge of atoms when electrons are lost? Explain why.</p><p>6. What is the charge on the overall compound when electrons are transferred? Explain why.</p><p>7. When electrons are lost, what happens to the atomic radius?</p><p>8. What is the charge of atoms when electrons are gained? Explain why.</p><p>9.
