Hey, everyone. So in this video, we're gonna take a look at some of the chemical bonds that exist within the main group elements. Now, ionic bonds also fit under this type of chemical bond, but we're not gonna be paying attention to those here. We're going to say the major intra molecular chemical bonds are metallic, covalent and covalent network bonding here. If we take a look, we have our periodic table in blue, we have our nonmetals in red, we have our metals and in green, we have our metalloid. We also have some other shading such as these orange borders as well as these purple ones, which we'll talk about. Also look at our periodic table and see that we have our transition metals in this pit right here. Now, we know that this pit is much larger and has more elements. But again, we're not paying attention to the transition metals. We're looking at our main group elements. So coming back up here, we'd say that metallic bonding is indicative of metals. It's in the name. Next, we have coal bonding. This is typical for a majority of the nonmetals. Our metalloid are the elements that do covalent network bonding. Now, of course, in chemistry, there are exceptions. The first one happens to be carbon, although carbon is not a metalloid because it's not in a green box, it is the only nonmetal with covalent network bonding. Also, we'd see that tum and Acetin, although they're metalloid, they do not possess cove of network bonding. So here we'd say that Tali and Acetin go here, you don't have to go into further detail in terms of this. Just remember, they don't possess covalent network bonding unlike the other metalloid. Now recall that we've talked about this in previous chapters. When it comes to covalent network elements, they have the greatest overall bo boiling points and melting points amongst the elements of the periodic table. So just keep this in mind while we're taking a look at our main group elements of the three major types of inter chem intermolecular chemical bonds that we care about are metallic covalent and covalent network bonding.

In this example, it says to identify the element that is expected to have the highest melting point. If we take a look here at our options, we have iodine, magnesium, bromine carbon and sodium. If we take a look, we know that one of these elements is capable of doing covalent network bonding. Because remember they're the ones that have the highest general boiling points and melting points. If we take a look back at the periodic table from earlier, we'll see that carbon is the only element out of this list that's given that has the potential to create covalent network bonding. This will result in it having the highest melting point in this list. So here our final answer is option D.
