here we can say that the strength of a binary acid is based on the electro negativity, which I'll abbreviate as Ian or size, which is really the atomic radius, which I'll abbreviate as they are. Of the non note. Now, remember we're looking at a periodic table as we head towards the top right corner of the periodic table, the electro negativity will increase and our atomic radius world decrease. Now when it comes to the periodic table, we don't give electro negative values to the noble gasses. Flooring is the most electro negative element on the periodic table, with a value of four point up. Now, for elements in the same period or row, then we look at their electro negativity. We're going to say here, the greater the electro negativity than the more acidic the acid. So let's say for example, I'm comparing CH four, B, H 3 & H. F. So if we look here, B, C and F, they're all in the same roar period with one another. And we would say here the greater the electron activity. The more acidic, boring we just said is the most electro negative element on the periodic table. So a check would be the most acidic out of these three options. Now, if they're in the same in the same group or column, then instead we look at their size, we're gonna say the bigger or the greater greater the atomic radius than the more acidic. So let's say we were comparing hcl hbr and H I. So C A B. R. And I as we go up the group, the atomic radius gets smaller. So you become less acidic i is larger than BR and Cl because it's lowered down the group since it's larger, it's more acidic. So H. I would be the strongest asset out of these three. Alright. So if they're in the same row, we look at electro negativity. If they're in the same group, then we look at size. But let's say they're not in the same group or ro what do we do that? Well, if they're separated by only one row from each other, then we look at their electro negativity. Alright, so how do we do something like that? Let's say we're looking here at Mm Let's say we're looking here at NH three versus H. To us. So N. Is here as is here they're not in the same role when they're not in the same group. We look at electronic activity, nitrogen is more electro negative than sulfur. You don't recall that. Make sure you go back and take a look at my video dealing with the periodic trend of electro negativity. So as a result of this, this should be a little bit more acidic than this. Now, let's say that they're separated by more than one role from each other. If they're separated by more than one role from each other, Then we're going to say here that we look at size. Okay, so let's say we're comparing let's see we're comparing NH three versus H. Two T. They're not separated by one road from each other. This is in row two. This is all the way down here. In row four size is more important, since delirium is lowered down than nitrogen is, it's larger and therefore this would be more acidic. Alright, so just keep these trends in mind when trying to compare different binary acids to one another.
