How to Write Compound Formulas from Names:

Step 1:

What type of elements are present?

Metals are on the left and nonmetals are on the right of the periodic table.

left + right metal + nonmetal

right + right nonmetal + nonmetal

transition metal + nonmetal

metal + polyatomic ion

ionic compound

charges of ions in each group 1 = 1+   2 = 2+   13 = 3+   15 = 3-    16 = 2-    17 = 1-         

balancing charges of ions to make ionic compounds neutral

polyatomic anions suffixes:       -ate       -ite (BFF 2.0)

transition metals (roman numeral tells you the charge amount)

copy formula (with charge) from BFF 2.0. Balance charges

Write the + charge amount and balance charges.

no ions present (no charges) prefixes tell you the number of each atom's subscript

prefixes: 1 = mono 2 = di 3 = tri 4 = tetra 5 = penta 6 = hexa 7 = hepta 8 = octa 9 = nona 10 = deca

covalent compound
