Question

an atom of element has 2 electrons in the k shell and four electrons in the Shell shell. what is the atomic number of the element. identify the element and write the electronic configuration

Answer 1

The atom is carbon. (2,4)

Answer 2

Hi....
The element has 2 electrons in K shell and 4 electrons in L shell....
So atomic number(Z) = sum of total electrons or protons....
So Z = 2+4=6....
Now the Element with Z=6 is "CARBON"..
and its configuration is 2,4 or 1s^2 2s^2 2p^2....

Hope this helps you.... ☺
