So the transition metals represent elements found in the D. Block of the periodic table. So remember your D. Block represents this portion of periodic table. Now those represent our transition metals. They can be further broken down into your energy transition metals. Remember we find those within this portion of the periodic table. So these two additional roles are found between L. A. And H. F. And A. C. And R F. Now if we're talking about the periodic table remember we have our main group elements or our group A. Elements. So this would group B. Group one A. To A. This since three a. For a all the way to eight a. The transition metals themselves are known as your group B elements. But here it starts off as three B. And then this is 4B five B, 6 B, seven b. And then 8, 9 and 10. They are part of eight B. And then we have one B. And to be here we're going to say. Whereas the main group elements show similar chemical behaviors because of their valence electrons. Their transition metal similarities are treated differently. We're going to say transition metals show great chemical similarities in both their horizontal periods or rows and their vertical groups families or what we call columns. Okay now we're gonna say in the gradual addition of electrons to transition metals. New electrons are added to the inner core electrons which do not participate in chemical bonding. So we have f electrons f orbital electrons are being added deorbit electrons that are being added. This causes these transition metals to behave very differently than what we usually see with main group elements. Now we're gonna say for transition metals, each additional electron is added to our D block orbital's while for the land tonight and the actinides, they're added to the F block orbital's. Remember your land tonight? Are this row here and your actinides are this role here. So these are just some basic things that we've seen before. Together in the past when discussing the periodic table. Now, we're gonna play play closer attention to our transition metals themselves.
