So you must recognize the type of compound before you try to name it. The two types of compounds we will focus on first are ionic compounds (formed from positive and negative ions) and binary nonmetal compounds (molecular compounds). Additionally, some compounds (H2O, NH3, CH4, etc.) simply have common names that must be memorized. Introduction Writing formulas and naming compounds can be confusing because there are different types of compounds that follow different rules.
