Binary compounds metal and nonmetal
Another feature of the periodic table indicates that metallic behavior increases as you travel down a group and decreases as you go from left to right across a row. This will be important when we get to naming covalent binary compounds. All binary compounds are named with the more metallic element listed first and the more electronegative element listed second. Replace the ending of the electronegative element with -ide and you are pretty much on your way to naming your compound.
Then write the nonmetal element name second replacing the last three letters with -ide. Metals in the transition group often have multiple oxidation numbers. If your metal falls in the transition groups make sure to include Sn and Pb , then use Roman numerals to identify the oxidation number. Then write your non-metal element second with an — ide ending.
Covalent binary compounds are composed of two nonmetals. Identify the location of each element on the periodic table. When writing the compound, list the more metallic element first. The only exception is when a halogen is pared with oxygen, write the halogen first. This means that in a row, the lower number is more metallic and in a group, the higher number is more metallic. Use Greek numerical prefixes i.
If there is only 1 atom in the first element, you can drop the word mono-. The second word ends with -ide and always has a prefix.
