An atomic cation with a charge of +1 has the following electron configuration: 1s^2 2s^2 2p^6 3s^2 3p^5 what is the chemical symbol for the ion? how many electrons does the ion have? how many 3d electrons are in the ion?

Answer :

The chemical symbol for the ion is,

The total number of electrons present in the ion = 17

There is no 3d electrons are in the ion.

Explanation :

Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom are determined by the electronic configuration.

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

As per question the electronic configuration of cation is,

As 1 electron is added in this configuration then the electronic configuration of element will be:

The total number of electrons = [2 + 2 + 6 + 2 + 6] = 18

The atom having atomic number 18 is argon.

The chemical symbol for the ion is,

The total number of electrons present in the ion = [2 + 2 + 6 + 2 + 5] = 17

As we know that argon is a noble gas. So, argon do not possess d-orbitals.

Thus, there is no 3d electrons are in the ion.

a is the answer
