Question

how to find no.of electrons in each shell​

Answer 1

Answer:

What you do is you put 2 in the first shell then put the remaining electrons in shell 2 not more than 8, then if anything remains then put it in the 3rd shell with a maximum 8, then put the remaining in the 4th shell

Explanation:

If you want to find the number of electrons for an element with 13 electrons.

First, you put 2 electrons in the first shell (11 electrons remain)

Then you put 8 electrons in the second shell (3 electrons remain)

then you put the remaining 3 electrons in the third shell.

Hope this helps you :)
