24. Which set of properties is most characteristic of
transition elements?
A) colorless ions in solution, multiple positive
oxidation states
B) colorless ions in solution, multiple negative
oxidation states
C) colored ions in solution, multiple positive
oxidation states
D) colored ions in solution, multiple negative
oxidation states

The set of properties is most characteristic of  transition elements when it is colored ions in solution, multiple positive.

The following information should be considered:

Therefore we can conclude that The set of properties is most characteristic of  transition elements when it is colored ions in solution, multiple positive.

C.

Explanation:

Transition elements  like,  for example,  iron:

Fe2+  green colored in solution.

Fe3+  brown colored in solution.

i believe it is 40–40–20%

explanation:

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
