Magnesium (Mg) has two electrons in it's lowest (s) orbital.
6.86x10^20
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
