Which of the following are true about transition metal elements ?
(a) As the atomic number increases for d-block transition elements, electrons are in general added to an inner d orbital
(b) Metals in high oxidation states tend to be good reducing agents
(c) A common oxidation state of manganese is +4
(d) Going across a period the atomic radii does not change a great deal.
(e) As the atomic number increases for the lanthanides and actinides transition metal elements, electrons are added to an inner f orbital.
Answer:
Id say C since Manganese can be seen in its Mn(IV) oxidation state as MNO2 when water reacts with Manganese.For each precipitate formed, write a double replacement reaction?
