Question
Purpose: To practice naming and writing formulas of ionic compounds and to learn about molecular compounds and their naming. Introduction: Part 1: Ionic compounds By now you have watched this week's videos on naming compounds and writing formulas. This is simply more practice! There are a few ions in the report sheet that you probably haven't seen before. However, we can draw some parallels to help us remember. We know Cl Chloride Clo Нуроchlorite Clo, Chlorite ClO, Chlorate Clo, Perchlorate We can follow this pattern above for other halogens like bromine and iodine. Br Bromide Iodide BrO Нуpobromite IO Нуpoiodite BrO, Bromite IO2 Iodite BrO; Bromate IO3 Iodate BrO4 Perbromate IO4 Periodate There are more similarities observed within families on the periodic table. Both sulfur and selenium form similar bonds with oxygen: SO," is sulfate; SeO, is selenate. Phosphorus and arsenic also form analogous ions with oxygen, such as phosphate, PO,", and arsenate, ASO,*. Part 2: Molecular Compounds Molecular compounds (also sometimes called covalent compounds) are made up of all nonmetals. We will focus on the binary molecular compounds in this lab, meaning ones that are made of only two elements. Since nonmetals are on the right side of the periodic table, in order to reach octet they have to gain electrons. When creating a compound from these elements, we are putting together atoms that all want to have extra electrons and nobody wants to give up any electrons. How can this be accomplished? By sharing! The important consequence of sharing electrons is that they are no longer traded between atoms; if electrons are not added or removed, there are no charges that could help us figure out how to put the atoms together in a formula correctly. Instead, we have to rely on names. When naming molecular compounds we have to use prefixes to indicate how many atom there are. The prefixes are Mono- 1 Неха- Di- Нepta- 7 Tri- 3 Octa- 8 Tetra- 4 Nona- 9. Penta- 5 Deca- 10 The rest of naming is straight forward. We name the first element by its name, then the second element ending in -ide. Finally, we go back and add prefixes that correspond to the number of atoms in that compound. Examples: N2O4 There are 2 nitrogen atoms and 4 oxygen atoms in this molecule. So the name is dinitrogen tetroxide. Note that "a" from tetra is sometimes dropped to simplify pronunciation. P,O10 There are 4 phosphorus atoms and 10 oxygen atoms in this molecule. The name is tetraphosphorus decaoxide. Cl207 There 2 chlorine atoms and 7 oxygen atoms in this molecule. The name is dichlorine heptaoxide. Procedure: Now it's time to practice! Name and write formulas for ionic and molecular compounds in the report sheet. The ones that say “skip" are acids and they follow a different naming convention all together, so don't worry about those. I can't emphasize enough how important it is to be able to write formulas and names correctly and how much easier and smoother the rest of the semester will go if we get really good at this from the start.
