If K and L shells of an atom are full, then what would be the total number of electrons in the atom?

Imagine an atom as a tiny solar system, with electrons orbiting around a nucleus like planets orbiting the sun.

Now, atoms have different layers or ‘shells’ where these electrons reside. The two innermost shells are commonly named K and L shells. Each shell has a specific capacity for electrons.

The K shell, being the closest to the nucleus, can hold up to 2 electrons. Moving outward, the L shell, the next electron layer, can accommodate a maximum of 8 electrons.

So, what happens if both the K and L shells are completely full, packed with the maximum number of electrons they can hold?

Well, in this scenario, the K shell is holding its maximum of 2 electrons, and the L shell is also at its limit with 8 electrons.

To find the total number of electrons in this atom, we simply add up the number of electrons in the K and L shells: 2 (from the K shell) + 8 (from the L shell) equals 10 electrons in total.

Therefore, if an atom’s K and L shells are completely filled, the total number of electrons in that atom would be 10. This knowledge helps us understand how many electrons an atom can hold in its specific electron shells, guiding us in unraveling the mysteries of chemistry and the behavior of elements!”

Understanding the electron arrangement within atoms, especially regarding shell capacities, is crucial in comprehending the behavior and reactivity of elements in various chemical reactions.
