Consider the electron configuration. A box holds an up and a down arrow. A box holds an up and a down arrow. A box holds an up and a down arrow. A box holds an up and a down arrow. A box holds an up and a down arrow. A box holds an up and a down arrow. A box holds an up and a down arrow. A box holds an up and a down arrow. A box holds an up arrow. 1s 2s 2p 3s 3p Which element has this electron configuration?

The Argon () has this electron configuration.

Explanation:

The question is wrong. The correct electron configuration is :

The electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.

The letters s,p,d and f are called the orbitals.

The numbers 1,2,3,4,5,6 and 7 are called the levels.

The maximum numbers of electrons that the s-orbital can hold is 2 electrons.

The maximum numbers of electrons that the p-orbital can hold is 6 electrons.

The maximum numbers of electrons that the d-orbital can hold is 10 electrons.

The maximum numbers of electrons that the f-orbital can hold is 14 electrons.

The order in which the orbitals are filled is :

1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p-6f-7d-7f

To identify the electron configuration of an element we need to count and sum the exponents of its orbitals.

The electron configuration is :

Has the following sum of exponents :

Therefore the total electrons of the element is 18 electrons.

The element that has 18 electrons is Argon ()

it is the most commonly accepted one

elements make up everything, and they combine to make compounds.

the answer is c
