Caesium has six electron shells.
Bromine has FOUR energy Levels.
Arsenic has 8 levels of energy.
There are 3 energy levels in Silicon. Which ever row it is in the Periodic Table, that is how many energy levels it has. The structure is 1s2 2s22p63s23p2
Silver has 5 energy levels. 😄
Platinum has six energy levels.
it is in the second period. so boron has 2 energy levels
Caesium has more electron levels than rubidium, because the electrons are further away the attraction between the outer electrons and protons in the nucleus is less. But that's not just the answer. There is also a thing called electron shielding, the negative charges, of the electrons in the energy levels closer to the nucleus, sort of repel the outer electrons so they can't get closer to the nucleus. Since the electrons are further away and have the attraction from the positively charged nucleus reduced, it takes less energy to break the attraction for caesium than rubidium.
