Hi there.
00:02
This question is asking us about the naming of binary compounds.
00:09
Binary compounds refer to compounds composed of two elements or two ions.
00:17
If it's a molecular compound, the binary compound is held together by covalent bonds, and it's composed of two non -metal elements.
00:37
If the compound is ionic, it is composed of, of two ions, a cat ion, which is the positive ion, and an anion, which is the negative ion.
00:53
Cateons can be formed from metals, or they can be polyatomic ions.
00:59
Anions are formed from non -metals, or they can be negative polyatomic ions as well.
01:08
Okay, so we have two different naming systems here.
01:13
For molecular compounds, we have to use prefixes to represent the subscripts.
01:20
And we change the ending of the second word, the second element to ide.
01:25
In ionic compounds, we do not use prefixes to represent the subscripts, but we still change the ending of the second element to ide.
01:36
So let's look at our answer options here.
01:37
There are four of them.
01:38
So i am just going to number them, one, two, three, and four.
01:42
So we know which one we're talking about.
01:45
And let's look at the first one.
01:46
First one says, in ionic compounds, the ending of the second element changes to ide, but not in covalent compounds.
01:54
Well, that is false because we change that ending of the second element for both types of compounds.
02:07
Therefore, the second statement here says in covalent compounds, the ending changes to id, but not in ionic compounds.
02:14
Well, that's, again, false because as we just said, we change the ending of the second element to ide.
02:21
In both types of compounds...
