1. Ionic compounds are usually   soluble in alcohols.   soluble in water.   soluble in ethers.   soluble in aldehydes.   Hint Half-n-half Clue   2. Inert gases do not react with any other element because   their outermost electron level is filled with 8 electrons.   their nucleus is very small.   the pressure is not high enough.   the temperature is not high enough.   Half-n-half Clue   3. High solubility of alcohol in water is due to the formation of   ionic bonds.   paramagnetic bonds.   hydrogen bonds.   covalent bonds.   Half-n-half Clue   4. Which of the following compounds is covalent?   NH3   MgCl2   KCl   LiCl   Half-n-half Clue   5. Two or more atoms combine to form   a molecule.   a cation.   an anion.   an ion.   Half-n-half Clue   6. Na+ combines with Cl- to form the compound NaCl. The charge on NaCl is   neutral.   negative.   a function of the conditions of formation.   positive.   Half-n-half Clue   7. In an ionic bond, the two elements   borrow electrons.   share electrons.   polarize electrons.   exchange electrons.   Half-n-half Clue
