Does the electron move to next shell only when the total energy is obtained or simultaneously with each eV??

Question

I mean...that..when electron is excited..it gains energy and moves to higher energy level. But this transition is done only when the total required energy is gained or its in between the two shells...as it slowly gains energy....and ultimately reaches the destination shell when the required energy is obtained.>??!!

Answer 1

Energy distrubition of electron in shells is quantiesed and defination of quanta is "The smallest amount of a physical quantity that can exist independently" and energy somes in quanta, i.e. in discret packents....so if u think of cooking gas as energy, in terms of shells it is recived more like cylinder (specific ammount) and not like in you gas like (continues)

Energy of light is also quntised.
E=hf
where E = energy
h = plank's contant
f = frequency
so as the freqency increases the energy of photon increases.

This principal is used in fluorescent light. The electrons of the noble gas traped inside the tube are exited (in higher shells or energy level) as they return to their normal shell they release this energy in the form of photon

similarly solar cells use this principal, u can check it out on the web 2 hav a deeper understanding

Answer 2

The electron must receive energy from outside its atom in order to bump it up to the next shell, also called an excited state. This energy can come from a stray electron, a photon, or a flash of light. Electrons in an excited state don't stay there for long. They quickly move back to their neutral state by releasing energy in the form of a photon.

Answer 3

It can't "be " between the 2 shells as it gradually gains energy, that is the definition of quantized energy. It's not gradual, it's a jump. That discovery is in fact partly what led to quantum mechanics.

(I have quotes around "be" because it's hard to say where it ever is or if it "travels" or just appears in a new spot)

Answer 4

It jumps, once it receives/gives off a certain quanta of energy it jumps from shell to shell. This is basis of photoelectric effect and spectral lines.

Answer 5

Only when enough energy is obtained

Answer 6

only when sufficient energy is gained

Answer 7

only when all the energy required is obtaind
