What is the electronic configuration for sodium

2,8,1

Explanation:

The atomic number of sodium is 11.

So first u have to remember somethings.

I assume that u r in 9th, sir.

So I'll explain some basic things.

While arranging the electronic configuration, in the first shell there can only be a maximum of 2 electrons.

In the second shell there can only be max of 8 electrons.

In the third there can only be a max of 18.

U just have to remember this.

So now u just have to arrange the atomic number of an element, in this case sodium into what I said.

First 2,then 8.

Now wait. Check how many electrons u have covered, till now u have covered 10 electrons.

U need to arrange one more.

So it's 2,8,1

I hope this satisfies you.

If u have any further questions please let me know.

I hope u will make this the brainliest answer and follow me.

With best wishes, joel
