what is the ground-state electron configuration of a neutral atom of nickel? This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you Electron Configuration for Ni, Ni2+, and Ni3+ (Nickel and Nickel Ions). Following along are instructions in the video below:
This video. Well write the electron configuration for nickel. And.
Then the nickel 2 2 plus. And nickel 3 plus. Ions.
So to do that lets start out nickel and when we look on the periodic table heres nickel. We can see that its atomic number thats 28. So that means it has 28 protons thats the atomic number atomic number equals protons.
We also know this is a neutral element. It doesnt have the after it so this is neutral nickel. So the protons will equal electrons.
We have 28 electrons to write the electron configuration here for nickel. We use this periodic table. We have the orbitals theyre broken up into this different blocks.
Thats very helpful you can also use this chart. Theres a link in the description. How to do that i prefer this method will start with 1s so put our 1s here s.
Can hold up to two electrons 1 s. 1 1. S.
2. And then we go to 2 s. 2 s.
1 2 s. 2. And weve used four electrons.
We have 28 after the 2s we go over heres the 2 p. 2p. The peas can hold up to 6.
So well put 6 in there weve used 10 electrons 3s2 3p6 and then from 3p. We go to the 4 s. 2.
Weve used 20. We only need 28. So for the 3 d d can hold up to 10.
But we dont need 10. We only need 8 to get a total of 28 electrons so well just go 3 d. 8 and thats the electron configuration for nickel neutral nickel as found on the periodic table youll often see the electron configuration written this way.
But since were getting further into the periodic table here. Its probably better to write it like this where we have the 3 d. Before the 4s this more accurately represents how the orbitals fill and then when we have ionization when we form ions.
We lose this 4s first so well write it like this either ways probably ok they both describe the same orbitals. Though lets write this in a condensed notation. So nickel is 3 d.
8. So lets put that here. 3.
D. 1. 2.
3. 4. 5.
6. 7. 8.
Thats where nickel is on the periodic table. So well go to the noble gas. Before nikhil thats argon right here then we write ar and we put it in brackets and then we write what comes after ar.
We have 4s1 4s2 and then we have up to three d8. So thats the condense notation for nickel. Lets use this to write the electron configuration for ni 2.
Plus. And then ni. 3 plus.
So you remember that we had the 4s written after the 3d. Lets do that so for ni 2. Plus.
That means that weve lost two electrons you lose electrons. Which are negative. You become positive so we have ni 2 plus.
We lost two electrons so lets just get rid of these electrons here in the 4s. 2. That will give us this notation.
Here. Where we end in the 3d 8. For the nickel 3 plus.
Weve lost a total of 3 electrons. Here so we get rid of our 4s. 2.
And well get rid of one of the electrons in this d orbital here thatll give us 3 d. 7. So thats it these are the electron configurations for nickel.
And the nickel 2 plus. And nickel 3 plus. Ions first you write the neutral element.
And then you remove electrons depending on what the charges. This is dr b and thanks for watching. .
