So remember, type 2 metals are metals that possess multiple charges. Now we're going to say most transition metals have varying positive charges because of their electron arrangements around the nucleus. Now there's going to be more advanced explanations for this later on, but we'll discuss them in much later chapters. So just remember, when it comes to type 2 metals, a majority of them are the transition metals. They have multiple charges.
So here, if we take a look, we have some of the most common types of transition metals, and what we need to realize is that although many of them have multiple charges, there are quite a few that do possess only one charge. So for example, scandium, which is in Group three or three B, it's 3+, and there's some similar chemical properties going on for elements within that group. Because scandium is 3+, that means the other metals that are in this group with it are also 3+.
But then of course, when you look at other transition metals, you're going to see a bunch of charges, like manganese, for example, could be 2+ 3+ 4+ 5+, or even 7+. Now the way we're able to tell which one of these charges manganese will have will be dependent on the other element it's connected to. We'll learn about that later on, but just realize here that these transition metals are called transition metals because they have a bunch of possible charges.
Now, besides the elements in Group 3B or three, we also have silver, cadmium and zinc, although their transition metals as well, they also have only one particular charge. So silver, when it's an ion, it's going to be 1+. Cadmium and zinc, they're both in the same group again, so they're going to be similar to each other. Both of them will be 2+ when they do have a charge.
So again, transition metals, a lot of them have multiple possible charges and because of that, they're characterized as being typed 2 metals. Some of the transition metals, the ones in red, they possess only one charge. They are transition metals, but they're not type 2 metals because they don't have multiple charges. So keep this in mind when we're confronting different types of transition metals. Some have the potential to have multiple charges.
