![]() International Union of Pure and Applied Chemistry, and they So that's one way to thinkĪbout the transition metals, but that way is maybe a littleīit too general sometimes. So you have to understandĮlectron configurations for this video. So these are the elementsįound in the d block, right? So we're talkingĪbout d orbitals here. In here, some people consider these to be They're talking about elements found from Would be when some teachers say transition metal, There are two ways to thinkĪbout transition metals. With the definition for a transition metal. Hope that helps.Ĭlassification of elements into groups on the And finally their valence electrons are in p-orbitals as opposed to being in d-orbitals for transition metals. They also end up having lower boiling points compared to transition metals. ![]() This means they are less likely to form metallic bonds and more likely to form covalent bonds which is a decrease in their metallic nature and a decrease in electrical conductivity compared to transition metals. ![]() So it's not a completely agreed upon region in the periodic table.īut in general, we can say that post-transition metals have a greater effective nuclear charge dude to the increase in protons compared to transition metals. However some sources are more inclusive and include metals such zinc, cadmium, and mercury and even some include metalloids such as germanium. Most sources include gallium, indium, tin, thallium, lead, and bismuth. So first when we talk about post-transition metals, we should be aware that different textbooks will have different elements included in this group. ![]()
