# How many electrons can be in each shell?

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Beside this, how many orbitals are in the 4f subshell?

The subshell has one orbital for a total of 2 electrons. The subshell has three orbitals for a total of 6 electrons. The subshell has five orbitals for a total of 10 electrons. The subshell has seven orbitals for a total of 14 electrons.

How many electrons are in 4f?

The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.

How many electrons are in the 5d Subshell?

The fourth shell has 4 subshells: the subshell, which has 1 orbital with 2 electrons, the subshell, which has 3 orbitals with 6 electrons, the subshell, which has 5 orbitals with 10 electrons, and the subshell, which has 7 orbitals with 14 electrons, for a total of 16 orbitals and 32 electrons.
