Why do principle quantum number starts from K?

Answer 1

Electrons are ruled by laws of quantum mechanics, which determine probabilities for finding electrons in any particular spot around nucleus. What we call the K shell is only part of space nearest the nucleus in which the probability for an electron's being found is the biggest. In that shell, the energy of electrons is the lowest, and that is why electrons will spend most time there, because only two electrons can be in that position at the same time, while the rest of them have to be placed in higher shells. See the Web Links to the left of this answer for more about how this naming convention began

Answer 2

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. He noticed that atoms appeared to emit two types of X-rays. The two types of X-rays differed in energy and Barkla originally called the higher energy X-ray type A and the lower energy X-ray type B. He later renamed these two types K and L since he realized that the highest energy X-rays produced in his experiments might not be the highest energy X-ray possible. He wanted to make certain that there was room to add more discoveries without ending up with an alphabetical list of X-rays whose energies were mixed up.

As it turns out, the K type X-ray is the highest energy X-ray an atom can emit. It is produced when an electron in the innermost shell is knocked free and then recaptured. 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.

Answer 3

because the scientist who discovered quantum number his first letter of name is k.the name of scientist i am missing.

Answer 4

K-shell make-up electrons of atom, they have an energy quantum number n = 1.
