Electron Configuration for ZN2+

What is the Electron Configuration for ZN²⁺?

 The given element is Zinc.

The symbol of the element is Zn.

Atomic number of zinc  – 30

Electronic configuration –   1s²2s²2p⁶3s²3p⁶4s²3d¹⁰ or [Ar]3d¹⁰4s²

Ground state electronic configuration(Neutral atom)-  1s²2s²2p⁶3s²3p⁶4s²3d¹⁰

Ion

An ion is an electrically charged particle formed by withdrawing  or adding electrons from a neutral atom or adding electrons to a neutral atom to make a negative ion.

We can determine the ion’s electron configuration by first figuring out the neutral atom’s electron configuration, then adding or deleting electrons based on the ion’s charge.

• If an ion has a positive charge, we have to subtract the electrons from the neutral electronic configuration of the element.

• If an ion has a negative charge, we have to add the electrons from the neutral electronic configuration of the element.

The given ion – Zn²⁺

2+ charge indicates substraction  of two electrons from neutral electronic configuration.

Zn electronic configuration – 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰

We have to remove two electrons from zinc neutral atom to get electronic configuration of

Zn²⁺ electronic configuration – 1s²2s²2p⁶3s²3p⁶3d¹⁰

Therefore, the electronic configuration of  Zⁿ²⁺ is 1s²2s²2p⁶3s²3p⁶3d¹⁰.
