Question

State and explain the Heisenberg uncertinity princepleon the basis of this princeple saw that electron can not exit with in nucleus
​

Answer 1

Answer:

Explanation:in Bohr's model he gave that an atom revolves around a fixed circular path and with fixed velocity

But for the this was contradicted as atom shows wave like nature , so it's impossible to locate fixed position and velocity at same time

Heinsberg uncertainty rule stated

"Fixed position and momentum/velocity cannot be located at a particular point of time"

DeltaX * deltaMv: h/4PIE

or

DeltaX * Delta V : h/4pieM. (Momentum=Mb)

Answer 2

Answer:

delta x * delta p≥ h/4pi

Explanation:

It is impossible to determine simultaneously the exact position and momentum (p=mv) of a particle like electron in an atom.

• Delta x = uncertainty in position
• Delta p= uncertainty in momentum.

Case 1. if delta x =0 then delta p = infinity

Case 2. if delta p=0 then delta x =infinity

and

delta p= m*delta v

• m= mass of the particle
• delta v= uncertainty in velocity
