Answer:
<h2><u><em>100 kcal of bond energy</em></u></h2>
<u><em></em></u>
Idk if this is the information you need but the energy level gets higher the farther you move down the Periodic Table. Every element in a vertical line has the same energy level.
Uh i did this because it made me curious... i may have done it wrong nothing happened
