Covalent And Ionic Bonds

Question 1

Describe an Ionic Bond

Answer 1

Metal –> nonmetal, transferred electrons High melting and boiling point, crystal lattice conductor of electricity hard and brittle, cations are metal and anions are nonmetals

Question 2

Describe a covalent bond

Answer 2

Nonmetal–>nonmetal, shared electrons low boiling and low melting

Question 3

Steps to binary Ionic Compounds

Answer 3

1. write symbols cation then anion
2. above the symbol write the oxidation numbers
   3.criss-cross
3. reduce and erase

Question 4
