Hey, guys, in this video, we're gonna take a look at some of the common types of properties dealing with transition metals. So here we're gonna say, like most main group, elements of transition metals possess similar physical properties. So some of the physical property that they share are common to many types of metals. For instance, their luster or shine medals in general tend to be shiny. They also have high densities. We're gonna say, here they're good at electrical and thermal conductivity. We're also going to say they possess high melting points and also hardness. Now, when it comes to conduction, there are some metals that work better than others. For instance, we're gonna say that silver or a G possesses the greatest electrical conductivity. So silver's usually ah, great way off. Basically transferring electrons from point A to point B. We're also going to say coming in second would be copper. Now, when it comes to melting point, we're going to say that tungsten or W, possesses the highest melting point at 340 degrees Celsius. Now you'll learn that Will you probably know from common knowledge that old lightbulbs used to have a tungsten filament in them before we moved on to more efficient means of using light bulbs. We're also going to say tungsten is were also used as huge, huge containers for melting off like hot iron or with an old school factories. You may actually, if you are in certain towns, you may still see huge furnaces, huge containers made of tungsten. We're going to say that while blank is the only medal that is a liquid at room temperature. So we say that this is mercury. Now, on the hardness scale, we're gonna say here that iron and titanium are strong or hard metals, meaning it would take incredibly high temperatures and a long amount of time for us to be able to melt them. Now, we're gonna say here that copper, silver and gold are considered to be soft metals, which makes sense if you think about it. In history, coins were usually made up of what copper, silver and gold. They're malleable, easier, easier to melt and fashion into different types of coins with different types of images on them. That's why ah, lot of money back in the ancient times was made up made up of these different types of metals. These soft metals now oxidation states. We're gonna say, Remember that transition metals possess variable charges. Certain transition metals can have multiple charges. Remember, we refer to them as type two medals. Type two medals just means they have more than one charge. Mag unease, for instance, has many different charges. So what? The type to metal. But there are some transition metals that possess only one charge. Remember that zinc is always plus two. Cadmium is always plus two. Silver is always plus one. They don't have variable charges. They only have one charge, so we refer to them as Type one medals. Type one medals have only one charge. Type two medals have more than one charge. So transition metals possess variable charges. And so the use of what we call reducing agents reducing agents have to be used in orderto identify which particular charge we're dealing with thes reducing agents donate electrons and, based on the number of electrons that the metal ion accepts, were able to determine the oxidation state of that transition metal. If those of you are lucky enough to decide to go into organic chemistry, you learn more and more about the different types of reducing agents that are used every day with inorganic systems
