The statement "<span>When an electron is added to a neutral atom of an element to form a negative ion, the resulting change in energy is referred to as the electron potential of that element." is false.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

Potential energy = (mass) · (gravity) · (height)
PE = (60 kg) · (9.8 m/s²) · (10 m)
PE = (60 · 9.8 · 10) · (kg · m²/s² )
PE = 5,880 joules
X-rays have the shortest wavelength of any waves on that particular list.
Gamma ray waves are shorter than X-rays, but they're not on that list.
Displacement is distance moved,so if you have your velocity in m/s you need your total time in seconds and multiply the two to get displacement so at 1.2m/s travelling (9.5*60(60seconds in a minute)=570 seconds is 570*1.2=684
