Transition Metals

Transition Metals

Atomic Radius:

        The atomic radius of Transition Metals increases by 1 shell as you go down the list. The number of electrons on the outermost shell never change. There are always the same number of electrons on the outermost shell of the atom.

Abundance on Earth:

       Some of the Transition Metals like Technitium (Tc) are manmade. The most abundant elements on the Earth are Iron, Copper, and Silver. They are easily found in nature, but the rare Transition Metals are not found as easily.

Uses:

        Transtition Metals are used for building materials, tools, vehicles, fighter aircraft, artificial hip joints, pipes in nuclear power stations and metal objects.

Reactivity:

        Transition Metals don’t react as bad as Alkali Metals, because they have a protective oxide layer which requires them to remove at least 2 or 3 electrons, whereas Alkali Metals only need to remove 1.

Other information:

        Transition Metals are both ductile and malleable. They are also conductors of electricity and heat. The three noteworthy elements are iron, cobalt, and nickel, because they are the only elements that are known to produce a magnetic field.

Melting and Boiling points:

        The melting and boiling points increase as you go down the list for the first 8 groups. On the last 2 groups, the melting and boiling points go down as you go down the list, but at the end they start going up again.
