Question

.DERIVE AN EXPRESSION FOR THE TIME TAKEN FOR AN ELECTRON TO GO AROUND THE ORBIT ONCE..

Answer 1

An electron doesn't 'go around the orbit', joe, it exists as an 'electron cloud'. There is no definite way to calculate the velocity of the electron, or find it's position because it exists as a wave and a particle. The electron has particle-like characteristics but there is no way you're gonna find the time for an electron to 'go around' the 'orbit'. Hope this helps.

are u 100 % sure????????

are u 100 % sure????????

Answer 6

........

Answer 7

A wave has velocity, but no definite position. A particle has no velocity, unless given a force, but definite position...The electron is both

Answer 8

wow .....thx dont go.. very helpful i hav some more questions

Answer 9

hey u thr???

Answer 10

okay

Answer 11

okay

Answer 12

DERIVE an expression for energy change that occurs when electron moves from orbit n1 to n2 and deduce condition for emission or absorption of energy.

Answer 13

wel mellinia i became ur 1st fan!!

Answer 14

..............

Answer 15

I don't know about the expression, but I know that for an electron to absorb energy, it requires to absorb a photon. To release energy, the photon is released. The electromagnetic force is completely mediated by light photons. The energy is quantisised, the electron can only emit energy in terms of light photons.

Answer 16

.....can u try to derive???

Answer 17

I lack the knowledge of the equations regarding the energy of a electron. Sorry..

Assuming that energy emitted is in form of electromagnetioc radiation and usiong E=hc/lambda ...arrive at an expression for wave no.(1/lambda) when transition takes place

Answer 23

from n1 to n2

Answer 24

melliinia??

Answer 25

Oh my. Sorry. I really can't help you here...This is advanced physics...:O

Answer 26

wl anothr??thn??

Answer 27

I'm really sorry...try posting it in the physics corner

Answer 28

??

Answer 29

Assume that an electron in H atom has been excited to a level n.Determine the maximum no: of emission. lines that can be observed when electron looses energy
