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 rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
