Compounds generally composed of NON METALS ONLY are called ______. Compounds composed of a combination of METALS AND NON METALS are called ______. One exception is______.

1. Which elements when bonded to each other form covalent bonds? A) argon and oxygen B) copper and carbon C) oxygen and sulfur D) potassium and cesium E) H & Na

2. Which substance below is most likely to possess covalent bonds?

A) PCl3 B) KBr

C) MgF2

D) ScCl3

E) SiO2

3. Which substance has ionic bonds?

A) Na2O

B) NCl3

C) H2S

D) CO2

E) SiCl4

4. Predict the chemical formulas of the compounds formed by the following pairs of ions: A) Cu+ and S2- B) Fe3+ and O2- 2+ 2- C) Hg2 and CO3 2+ 3- D) Ca and AsO4 + 2- E) NH4 and CO3 Naming Ionic Compounds 1 1) Name the first element, THE METAL.(If it is a roman numeral element, undo the crisscross to find the roman numeral) 2) Name the second element and if it is a nonmetal, change the ending to ide. If it is a polyatomic, name it.

1) NaI 2) FeCl3 3)(NH4)2CO3

4) Ca(NO3)2 5) Mn2(SO4)3 6) MnSO4

7) MgS 8) MgSO4 9) Mg(HSO4)2

Naming Covalent Compounds 1) Name the 1st element, 2nd element –ide 2) Prefix used to tell how many of each element. Mono- is only used on the last element. No charges involved – Use prefixes

1) PF5 2) N2O4 3) SCl2

4) BH3 5) NO 6) NO2

7) N2O 8) N2O5 9) P4S6

Writing Covalent Compounds

Write the correct symbol for the element names. Use prefixes for your subscripts. DO NOT crisscross numbers.

1) boron trihydride 2) dicarbon tetrachloride 3) sulfur dioxide 4) sulfur trioxide 5) iodine heptafluoride 6) tetraphosphorus decaoxide 7) sulfur hexafluoride 8) dichlorine heptoxide 9) phosphorus pentafluoride
