Answers:
1. What are the “prefixes” for covalent bonding?
mono, di, tri, tetra, penta- 5, hexa- 6, hepta- 7, octa- 8, nona- 9, deca (1-10)
2. What is the difference between ionic and covalent bonding?
see chart for this, but some are:
ionic bonding deals with metals and nonmetals, covalent only has non metals bonding
ionic has high polarity and high melting point, etc
3. When do you use Roman numerals for naming compounds?
when you are dealing with metals NOT in group 1 or 2 and NOT Ag, Zn, Al, and Sc
4. What is the ion name (with correct charge) typically formed by each element below?
a. oxygen (O2-)
b. iodine (I-)
c. aluminum (Al3+)
d. iron, 4 electrons lost (Fe (IV)) so Fe4+
5. Write the formula for the following ions:
a. sulfite: SO3^2-
b. sulfate SO4^2-
c. perchlorate ClO4-
d. hypophosphite PO2^3-
6. Write the formulas for the following compounds
a. hexaboron silicide B6Si
b. dinitrogen trioxide N2O3
c. phosphorus triiodide PI3
7. What is the name for the following compounds?
a. SiO2- Silicon dioxide
b. AgC2H3O2- siliver acetate
c. CCl4- carbon tetrachloride
