The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies. These energies were named as type A that is higher energy X-ray and type B that is lower energy X-ray.
When I was writing we ran into the inquiry “How many electrons are in an atom if the K-shells are full?”.
Therefore, if the K and L-shells of an atom are full, then the total number of electrons in the atom would be (2 + 8) = 10 electrons. K denotes the first shell (or energy level), L the second shell, M, the third shell, etc.
Solution Verified by Toppr K shell can accommodate a maximum of 2 electrons. L shell can accommodate a maximum of 8 electrons and M shell can accommodate a maximum of 8 electrons.
While reading we ran into the question “If k and l shells of an atom are full?”.
Best answer K shell becomes full with 2 electrons and L shell becomes full with 8 electrons . So, if the K and L shells of an atom are full, then it will have a total of `2 + 8 = 10` electrons in it.
Another thing we wanted the answer to was what is the total number of electrons in an atom with K?
K shell can accommodate a maximum of 2 electrons. L shell can accommodate a maximum of 8 electrons and M shell can accommodate a maximum of 8 electrons. Hence, If K, L and M shell of an atom are full, then the total number of electrons in the atom would be: 2 + 8 + 8 = 18 electrons.
Why is the first shell of atom called K and not a?
The names were coined by Charles Glover Barkla. He was studying the x-rays emitted by atoms when they are hit with high energy electrons [1]. He noticed that there are two types of characteristic x-ray lines produced, which have different energies.
Some have found that we all know that the first shell of an atom is named K. Why not A ? The names of the electron shells come from a fellow named Charles G. Barkla, a spectroscopist who studied the X-rays that are emitted by atoms when they are hit with high energy electrons.
Which shell of the atom has the minimum energy?
The shells begin from the centre and gradually move outwards. So K shell will always have minimum energy. The L shell is a little away from the nucleus so that it will have higher energy than the K shell.
Why does the innermost shell of an X-ray have a K-shell?
He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies . These energies were named as type A that is higher energy X-ray and type B that is lower energy X-ray. Later these energiers were named with different alphabets.
This innermost shell is now called the K-shell, after the label used for the X-ray. Barkla won the 1917 Nobel Prize for Physics for this work.
