Thermal energy is the energy associated with

Or in other words temperature being the actual answer but you gave him no options so he was close enough.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

did anyone actually do this? like if anyone has submitted this i rly need .
