What are transition elements?
Elements within the D-block in periodic table where the D subshells are being filled.
Give the electron configeration of Fe...
1s22s22p63s23p63d64s2
Which two transition elements have unexpected electron configerations and why does this happen?
Cronium and Copper, as the elements strive to having half filled subshells or full subshells in order to be more stable, therfore electrons move to fulfill this need.
Explain why scandium and zinc are not true transition metals...
Scandium has no 3d or 4s subshell and Zinc has 3d10 and 4s2 and are therefore completely stable.
What are the three chemical properties of transition metals?
Coloured ions, varible oxidation states, action as catalysts.
