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.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
