Question

2. what is the maximum number of electrons which can be held in the 5th shell of an atom? use the correct formula to find the answer​

Answer 1

Answer:

50 electrons

The third shell has the s, p, and d subshells ⟹ 2 + 6 + 10 = 18 electrons. The fifth shell has the s, p, d, f, and g subshells ⟹ 2 + 6 + 10 + 14 + 18 = 50 electrons.

Answer 2

Answer:

it says that the maximum number of electrons that can fit in any given shell is given by 2n². This would mean 2 electrons could fit in the first shell, 8 could fit in the second shell, 18 in the third shell, and 32 in the fourth shell.

However, I was previously taught that the maximum number of electrons in the first orbital is 2, 8 in the second orbital, 8 in the third shell, 18 in the fourth orbital, 18 in the fifth orbital, 32 in the sixth orbital. I am fairly sure that orbitals and shells are the same thing.

Which of these two methods is correct
