a. How many electrons will there be in the hypotransition metal series?
b. How many of the atoms will be diamagnetic?
c. Which electronic configuration in the series will have seven unpaired electrons?
d. What is the maximum number of unpaired electrons an atom can have in this series? Will thsi be a new record for atoms in the periodic table?
