What is the correct arrangements of electrons in various shells, sub-shells and orbitals in an atom?

Arrangements of Electrons in Shells, Sub-Shells, and Orbitals in an Atom

• The numbers are 2, 8, 8, 18, 18, and 32.
• The number of electrons in the nth shell is 2n2, for example, there are 8 exceptions to the rule in the second shell, which has 2*22 electrons.
• The following table lists certain elements’ electronic configurations:

Element	Configuration
	2, 8, 8, ….. type	nlx
Sodium (Na-11)	2, 8, 1	1s2 , 2s2 , 2p6 , 3s1.
Iron (Fe-26)	2, 8, 14, 2	1s2 , 2s2 , 2p6 , 3s2 , 3p6 , 3d6 , 4s2.

Summary:

What are the correct arrangements of electrons in various shells, sub-shells, and orbitals in an atom? (a) 2, 8,18, 8, 32 (b) 2, 8, 8,18,18, 32 (c) 2, 8, 8, 8,18 (d) 2, 8,18, 32, 2

The proper configuration of electrons in an atom’s numerous shells, subshells, and orbitals is 2, 8, 8, 18, 18, and 32. It is how electrons are arranged within an atom’s different shells, subshells, and orbitals.
