Let me first tell you that there are many elements considered to be transition metals. Which transition metal?

That's all about their shell / track. Because it is easy to explain, I will introduce the first 18 elements. It is a good example of advanced shell and orbital thinking. They have a lot of electrons and they distribute them in various ways. Normally, you can see that the transition metal is also shiny. Not all, we believe that you have seen pictures of silver (silver), gold (gold), platinum (platinum)

The transition metal can place more than 8 electrons in the housing, which is one of the outermost shells. Let's think about argon (Ar). It sets 18 electrons in order of 2-8-8.钪 (Sc) has only 3 points and 21 electrons, its configuration is 2-8 - 9 - 2. Wow! This is where it began. This is a point in the periodic table that allows you to put more than 8 electrons into the shell. You need to remember that these electrons are added to the penultimate projectile.

The transition metal can arrange 32 electrons in the penultimate shell. Like gold (Au), atomic number is 79, organization is 2-8-18-32-18-1. Of course, there are some rules. There can be more than 32 electrons without a shell. For the maximum number of electrons in a track, you can see that it is usually 2, 8, 18 or 32

Most elements can only be combined with other elements from electrons from the outer raft. Transition metals can be combined with other elements using two outermost shells / tracks. It is a chemistry that can be combined with various forms of elements. Why are they doing this? Knowing in detail, you can see that most transition elements actually have two insufficient shells. Whenever you have an unhappy shell, the electron wants to combine with other elements. Example: Molybdenum (Mo) with 42 electrons. It is configured as 2-8-18-13-1. 13 and 1 shell are not happy. These two trajectories can use electrons to combine with other atoms.

The 38 elements of Groups 3 to 12 of the Periodic Table of the Elements are called "transition metals". As with all metals, transition elements are both ductile and malleable, electrical and thermal. An interesting point of transition metals is that their valence electrons or electrons used to bind them to other elements are present in multiple shells. This is why they often show some common oxidation state. There are three noteworthy elements in the transition metal series. These elements are iron, cobalt and nickel, which are the only elements known to generate magnetic fields.

The elements of the periodic table are usually divided into four categories: (1) main group elements, (2) transition metals, (3) lanthanides and (4) acting elements. The main elements are active metals in the leftmost two rows of the periodic table and metals, metalloids and nonmetals in the right end row. Transition metals are metal elements used as bridges or transitions between the sides of the table. Lanthanide elements and active elements at the bottom of the table are sometimes called internal transition metals because their atomic numbers are between the first and second elements of the last two rows of transition metals.

Gallium is a late transition metal. These are metal elements between the transition metal and semimetal (nonmetal) of the periodic table. Post-transition metals have some properties of transition metals, but tend to be softer and worse results. Post transition metals include several boron elements - aluminum, indium and antimony - and tin (Sn), lead (Pb) and antimony (Bi). Gallium has several very unique properties. For example, it is solid at room temperature (about 77 F / 22 C) but still very soft, so you can cut it with a knife. In addition, it has a low melting point (10 degrees below room temperature) of 85.57 degrees Fahrenheit (29.76 degrees Celsius), so if gallium is taken in hand it melts from the warmth of your hands. When it is restored, it will set again
