Tungsten atoms produce characteristic x-ray emissions for electron transitions between the K, L and M shells. Given the information below, an electron transitioning from the M to the K shell will produce an x-ray with what characteristic energy?
Shell M: 2 Kev of IE (ionization energy)
shell L: 11 KeV of IE
Shell K: 70 KeV of IE
answer also: which is the closest to the nucleus?

Respuesta :

An electron from of the M shell occupying a hole in the K shell at 69 keV expelled as you move from the outside in to the inside will be moving to an energy levels with an ionization energy of 70 keV  -2 keV,

the periodic table, what is ionization energy?

The minimal energy needed to ionize an atom is sufficient to eject an electron from its ground state. Ionization energy has a periodic trend that rises across the chemical elements form top to bottom as well as from left to right.

Ionization energy: what is the rule?

As you move from left to right along a period just on periodic table, the initial ionization energy often rises. This is because when nuclear charge rises, the outermost electron becomes more tightly connected to the nucleus.
