naming ionic compounds
ionic compounds are formed when a metal and a nonmetal come together. think of it like a team - up where one player (the metal) gives away electrons and becomes positively charged (a cation), and the other player (the nonmetal) takes those electrons and becomes negatively charged (an anion). the opposite charges attract, forming a strong bond.
heres how to name them:
1. name the metal first. this is usually the first element in the formula. you just use its regular name. for example, in nacl,
a\ is sodium.
2. name the nonmetal second. for the nonmetal, you take its root name and add the suffix \-ide.\ so, \cl\ (chlorine) becomes chloride.
3. put them together! so, nacl is sodium chloride.
lets try another one: mgs.
- mg is magnesium.
- s (sulfur) becomes sulfide.
- therefore, mgs is magnesium sulfide.
what about metals that can have different charges? these are called transition metals, and they need a little extra help. we use roman numerals in parentheses to show their charge. for example, iron (fe) can be fe²⁺ or fe³⁺.
- if you have fecl₂, the chlorine ions each have a -1 charge. since there are two of them, the total negative charge is -2. to balance this, the iron must have a +2 charge. so, its iron(ii) chloride.
- if you have fecl₃, the total negative charge from three chloride ions is -3. this means the iron must have a +3 charge. so, its iron(iii) chloride.
naming covalent compounds
covalent compounds are different from ionic compounds because they are formed when two nonmetals share electrons. instead of giving and taking, theyre sharing partners. because they share in different ways, we need a system to show how many atoms of each element are in the compound. we use prefixes for this!
here are the common prefixes youll need to know:
- 1: mono-
- 2: di-
