Match each of the questions below with either "True" or "False" as appropriate.
-The metals with the highest ionization energies are most likely to be found in nature in the elemental state.
- Metals usually have higher melting points than nonmetals.
- Co(II) ion in water is blue.
- The electron configureation of Mn2+ is [Ar]4s23d3.
- All tetrahedral complex ions are high spin.
My answers are:
Please answer back if I might have something wrong...
Would you please go through and tell us why you think each answer is as you have it.
-The majority of metals are not naturaly made...so that is why the first one is false.
-Metals have higher melting points than nonmetals because the electrons are tightly pack into a solid form and is a fact in the book.
-Is true because I found it in a website but I can't post it because I don't own it.
-Is false because when is a + ion you subtract not add...so that is why it makes it false.
-This one I am not really sure because spining pairs are very tricky...so this is really confusing
