Ncl3 Compound Name

I hate chemistry! Why is NCl3 called nitrogen trichloride but why is MgCl2 called magnesium dichloride? 3

Why is NCl3 called nitrogen trichloride while MgCl2 is called magnesium chloride and not magnesium dichloride?

To update

Jay !! Al2 (SO4) 3 Why is it made of aluminum and not aluminum?

Don't try to recreate your name system.

If an element has more than one valence, we must differentiate between them according to the IUPC system. N has 3 and 5 valences, so nitrogen III chloride is the best. Mg has only one valence, so

Magnesium chloride is good, as is sodium chloride NaCl, but Fe2O3 is an oxide of iron and FeO.

Iron oxide II Al2 (SO4) 3 is only aluminum sulfate. (Al has a valence of only 3, all metals except z). You can see that the right system is very easy to use and you get more points. It's easy once you get into the habit of practicing.

Nitrogen trichloride is a molecular compound, so you need to use a precursor. Magnesium chloride is an ionic compound, so you must follow these principles. Mg is 2+ and Cl is 1. They must be removed to equal z. The same thing happens with Al2 (SO4) 3, it is an ionic compound. Al has a charge of 3+ while SO4 has a charge of 2. You need two Als, so 6+ and 3 SO4 to make 6. Just look at which item is in which column. Column 1 has 1+, column 2 has 2+, and so on. Halogens have 1 and column 6 has 2. Light gases always have 0. You just have to keep in mind things like SO, because they never end. My teacher let us take the test until we all had the right problem with the right rate and name.

Ncl3 Compound Name

NCL3 are nitrogen trichlorides simply because they are 2 non-metals. MgCL2 is called magnesium chloride because it contains both metals and non-metals. The same is true for AL2 (SO4) 3.
Sorry, you hate chemistry. There are three ways to name a connection:
1) Ionic compounds (metal / non-metallic compounds such as NaCl) where there can be only one charge for metal ions (in groups 1A, 2A and Al, Ga and In 3+ _Zn and in Cd 2+ and in Ag 1 +) By naming them metals and then the final idea sodium chloride 0, d always anion with 1 + and the column is always 2, which explains the formula of Na2SO4. Similarly with Al2 (SO4) 3, since it must be Al 3+ and SO4 2, that is, it must be Al2 (SO4) 3 so that 2X3 + = 6+ is balanced with SO4 with Al 3X2 = 6.
2) Ionic compounds with metals with different charges under different conditions. There are two different types of iron oxide, powder and red powder. They contain only iron and oxygen, so they are both iron oxides. Does it matter? One has the formula FeO while the other has Fe2O3. One way is to call them iron monoxide and other iron trioxides, but the scientific community in its wisdom (whatever it may be) chose to use names that indicate a charge on a metal ion. FeO has Fe with 2+ charge, hence we call it iron (II) oxide, and Fe2O3 has Fe with 3+ charge, which gives it the name Iron (III) oxide.
3) The rest are molecular compounds formed from non-metallic / non-metallic compounds like CO and CO2. Both are carbon oxides and hence carbon oxides, but do you need to differentiate between the two? Non-metals do not form ionizing compounds compared to non-metals, so the charge we talked about in (2) will not work. What we do for this is that we use the Greek prefix to provide carbon monoxide for CO and carbon dioxide for CO2 (we removed mono for the first elements and we just talk Not doubling the heads).
Shame on you Impossible to learn, not really. I now.
MgCl2 is an ionic bond and has a different naming principle, it is a bond between metals and non-metals.
But NCl3 is a covalent bond, a non-metallic to non-metallic bond, so it uses a prefix to indicate the amount of chloride.
Leave the key until you need to become a scientist.
