  14. Answer the following questions… • When a chemical bond forms, there is a attraction between two subatomic particles. What are these two particles? • In an EXOthermic reaction, energy is ALWAYS ________. • For an EXOthermic reaction, energy is always found on which side of the chemical reaction? • For a ENDOthermic reaction, energy is ALWAYS ________. • For a ENDOthermic reaction, energy is always found on which side of the chemical reaction? • When a electron is transferred, the atom donating the electron becomes ________. • What is the ONLY combination allowed for covalent bonds to form? • Metals always share a “______“ of mobile valence electrons. This is what allows electricity to flow.

  20. Answer the following questions… • Identify the compound associated with the given information: a. low melting point. b. hard object. c. nonelectrolyte. • When the following elements become ions, identify their new electron configuration? Which noble gas configuration does it match? a. Phosphorus. b. Rubidium (Rb). c. Bromine. • Identify the type of bond formed. Ionic or covalent? a. electronegativity difference = 2.7 b. metal + nonmetal. c. strong bonds formed. d. nonmetal + nonmetal. e. polyatomic ion + polyatomic ion. f. electronegativity difference of 1.0 • The greater the electronegativity difference between the 2 elements, the __________ the IONIC CHARACTER. • The closer the electronegativity between 2 elements to zero, the __________ the COVALENT CHARACTER. • If a compound of one metal and one nonmetal have a electronegativity difference of 1.2, would the compound be considered ionic or covalent? Why?
