Practicing Success
Assertion (A) : If the total energy of the electron in a H-atom is negative, then it would be bound to the nucleus. Reason (R) : Bohr model is valid for both one electron atom and multi-electron atom. |
A and R are both true and R is the correct explanation of A A and R are both true but R is NOT the correct explanation of A A is true but R is false A is true but R is false |
A is true but R is false |
Electron is bound to nucleus by electrostatic force of attraction. Total energy = K.E + P.E , Its negative means , its kinetic energy is not enough to break free form the orbit. Bohr model is valid for one electron atom only. |
