Answer: B) Helium Explanation: Helium has the highest First Ionization Energy in the Noble Gases group. Ionization Energy :: Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms. Atoms are more stable when they have full valence shells. Noble Gases have a very stable electron configuration, therefore, they have the highest amount of ionization energy within their periods. It decreases down a family because electrons farther from the nucleus are easier to remove. Ionization Energy levels of Noble Gases group in Descending Order :: He, Ne, Ar, Kr, Xe, Rn

Answer: C) 20 Explanation: Let the rquired number be 'P' According to the question, 100 x P100 = 20=> P = 20 x 100100 = 20 Hence, 100 percent of the number 20 is 20.   Now, you can also try for 20 percent of what number is 100 20 x P100 = 100=> P = 100 x 10020 = 500=> P = 500 Hence, 20 percent of the number 500 is 100.
