Transition metals!
What are they?
The 38 elements in between group II and group III of the periodic table are called transition metals.The name 'transition' derives from their position in the periodic table, as they act as a transition ['bridge'] between the group II and group III elements.
Uses of transition metals...:)
Some transition metals have several uses, especially for iron and copper. Transition metals also often form important alloys like iron in steel, zinc & copper in brass.
Transition metals are good catalysts for particular reactions.
[Note: Catalysts are substances that can be used to change the rate of a reaction.They are usually used to speed up the rate of a reaction. The catalyst itself is not involved in the reaction itself, so it is not changed or used up during the reaction.It stays in its original form even after the reaction is complete! :D]
The bonding of atoms in transition metals is relatively strong.As a result, they are strong metals with high boili
ng and melting points as well as high densities.They also have many electrons to carry energy, thus are effective in conducting electricity-chloride-purple-anhydrous-sunlight.jpg)
. Many of the transition metals are not very reactive to water or oxygen, but when they form salt compounds, the resulting substance tens to be coloured.For example, cobalt chloride is blue and titanium chloride is purple.
[THEREFORE THEY ARE VERY COLOURFUL METALS!!! YAY! :DDD]
