Answer:
Elements that have atomic numbers from 20 to 83 are heavy elements, therefore the ratio is different. The ratio is 1.5:1, the reason for this difference is because of the repulsive force between protons: the stronger the repulsion force, the more neutrons are needed to stabilize the nuclei.
The shot answer for this question is (a) True
<span>The electrons in the outer shell of Xenon are much further away from the nucleus than the electrons in the outer shell of Neon. The Xenon electrons are much less bound to the atom than Neon, and a strong electronegative atom like fluorine succeeds in tearing off an electron.</span>
