I would be difficult to remove an electron from a Noble or Inert Gas (also known as the group 8 or 0 elements). This is because they all have filled outermost shells and as such the outermost shell would be held tightly to the nucleus and as such make it difficult to remove. Examples Helium, Neon, Argon, Xenon, Krypton and Radon

In order to find the percentage change in mass, you must d<span>ivide </span>Change in Mass<span> by Initial </span>Mass<span>. After that, you divide the </span>change in mass<span> by the initial </span>mass<span> of your substance.
This calculation shows what proportion of the initial </span>mass<span> changed. To find the </span>percent change<span>, simply multiply this number by 100</span>

The amount of protons in a specific element do not change, for if the protons change, then the element themselves change. Therefore, no matter what, if the question specifies the element (i.e. Carbon) then the amount of protons will remain the same as seen on the periodic table.
Hope this helps!
