When a spring is compressed, the energy chaneges from kinetic to potential. Which best describe what is causing this change?

Potential energy is formed from the potential the spring has to spring up and decompress and as the spring compressed it created kinetic energy and lost that once it was compressed

Explanation:

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.
