Hello,
I have attached a periodic table to allow you to further understand my answer. We know elements are categorized in groups of Metals, Nonmetals, and metalloids. Let’s analyze each element. Sulfur is a nonmetal which mean it does not conduct well and does not have a good appearance, the same applies to all the other non metals on this list, including sulfur and helium. Copper is our only answer in which it fits and electricity can pass through/conduct easily. So our answer is copper. I hope this helps you with your assignment.
Kinetic energy is an object in motion, potential energy is the potential for energy. Energy is the ability to make change, so kinetic energy is in the process of impacting something else.

Co: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁷
Co(2+): 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁷
or....
Co: K² L⁸ M¹⁵ N²
Co(2+): K² L⁸ M¹⁵
It's false.the reason is explained in the picture
