why the shells of an orbit is name as k,l,m,n
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.
The shell is the principle energy level, and is defined as 1, 2, 3, etc. (or K, L, M, etc). An orbital is the spacial orientation of the orbit, such as px, py, pz, where the orbit is a p orbit, and the orbital is the x, y, or z orientation of that orbit. This is a mathematical expression of where the electron is most likely to be found. The electron cloud is more of a visual representation of the electrons surrounding the nucleus, and is based on the electron orbitals.
No, but the do orbit in a certain shell.
In science and physics, k-edge absorption is when the shell of an electron in that atom cannot eject the K shell electron. This typically occurs when there is too many photons occurring at once.
The center of an atom is a nucleus. In the center of the nucleus, there is protons and neutrons. Around the atom, is the shell. Using the shell, as an orbit is the electron.
Elements are in fact a bundle of energy if you will. I believe what your asking is How can you tell if an element will conduct electricity. If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor. Here's why: The atoms of a given element is composed of the protons, neutrons, and electrons. Electrons are the "electricity" part of an atom. These electrons orbit the protons and neutrons that are at the center of the atom. The electrons are in Valence shells, which is basically which orbit the electrons are on, the closest shell/orbit can contain only 2 electrons, and then it is said to be stable and full; the second valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full; the third valence shell/orbit can only contain 8 electrons, and then it is said to be stable and full also ect.... Now, if we took the third valence shell, and it only contained 1 electron, it is NOT stable and full, so this 1 electron/electricity-part-of-the-atom is free to float around to other empty shells. This is due to the fact that the electrons always want to be in a stable shell/orbit. Some atoms of certain elements naturally contain a full AND therefore stable outer valence shell, (the furthest shell/orbit away.) If an atom contains less the the required atoms for its outer shell to become full and stable, it is classified as a conductor.
They are named as K , L , M , N ... . Where in K is the first shell , L is the second shell , M is the third shell , N is the fourth shell and so on.
shell and orbit are same
speed of electrons varies from shell to shell . it increases from inner orbit to outer orbit
the formula for finding out the maximum number of electrons is dependent upon (2n2). n represents the shell, K,L,M,N,O, etc. So if the K shell is the question K is the innermost shell and is represented as 1, so 1 squared is 1, times 2 equals 2! And L is the second shell in the orbit, so 2 squared is 4, times 2 equals 8! M is the third, so 3 squared is 9 times 2 is 18! etc....
shell and orbit are same
The K shell is first shell closest to the nucleus.
k shell has two electrons because in the structure of an atom every shell has an capacity to have fixed number of electrons that why k shell has capacity to have 2 electrons.
K is the old symbol for the first electron shell in atoms (near the nucleus). The K shell contain max. 2 electrons.

K shell.
The orbit or electron shell closest to the nucleus is the 1s sub-shell. It can hold 2 electrons before the 2s sub-shell is filled. H and He have their electrons in this shell (the 1s)
A shell of an atom is meant to contain or hold an electron floating around the nucleus. They don't actually cover the whole atom. They're rings made of the electrons that float in orbit around the atom.but the answer is electron paths
