How many electrons are in ewch energy levels
joja [24]

Answer:

To determine how many electrons fit in each energy level, use the formula:

2n²

N is equal to the number of energy levels. Using this formula, we can determine that there are:

  • First energy level holds 2 electrons
  • Second energy level holds 8 electrons
  • Third energy level holds 18 electrons
  • Fourth energy level holds 32 electrons
  • And so on...

Keep in mind though, that for an atom's outermost shell, it can only contain 8 valence electrons due to the octet rule that states that an element only needs eight electrons in their outermost shell in order to be stable.
