NAMING REVIEW WORKSHEET Name ______
Complete the front and back of this worksheet. If you are given the name of compound, the following questions might help you write the proper formula.
1. Is it an ionic or covalent bond?
Ionic compounds contain metals, they must lose and gain the same number of electrons. Metals are left of the diagonal line.
Covalent compounds contain all nonmetals. Prefixes are used to indicate the number of atoms of each element in the compound. Do not worry about losing and gaining electrons, they are sharing.
2. What is the ending of the name?
ide endings indicate that the compound is binary, only 2 elements. The exception is the polyatomic ion hydroxide.
ate endings indicate that the compound contains a polyatomic ion. Check the back of the periodic table or textbook page 97.
3. Is the metal a transition element?
The ( ) after the name of the metal indicates the number of electrons the metal is losing.

If you are given the formula of a compound, the following questions might help you write the proper name.
1. Is it ionic or covalent bonding?
Ionic compounds contain metals, they must lose and gain the same number of electrons. Metals are to the left of the diagonal line on the periodic table.
Covalent compounds contain all nonmetals. Prefixes are used to indicate the number of atoms of each element in the compound. Do not worry about losing and gaining electrons, they
share.
2. Does the compound contain 2 elements or more than 2 elements?
Binary compounds contain only 2 elements and end with the letters ide. The only exceptions: When the polyatomic ion ammonium is used with 1 other element or when the
polyatomic ion hydroxide is used.
Compounds with more than 2 elements usually contain polyatomic ions. Check the back of your
periodic table or page 97 in your textbook for a complete list.
3. Is the metal a transition element?
Transition metals can lose different numbers of electrons. You must determine the number of electrons the metal loses and put that number in parenthesis after the name of the metal.
Name each of the following.
31. MgCO3 ______38. NiBr2 ______
32. CaO ______39. P2 O3 ______
33. MgO ______40. AlBr3 ______
34. ZnP ______41. MgSO4 ______
35. Be(NO3)2 ______42. Ca3(PO4) 2 ______
36. CO ______43. PBr3 ______
37. Fe2O3 ______44. Ni(OH) 2 ______
