Question

Wh energy is absorbed for the removal of electron from atom ?

Answer 1

Hi!

We know that unlike charges attract each other. Also that very system always tries to stay in or attend Minimum Potential Energy state.

When we remove the electron from the atom, energy is needed, due to minimum potential energy state of atom, which is absorbed.

Answer 2

To counter balence nuclear attraction for electrons.

Answer 3

The +ve nucleus attracts -ve electrons so energy is needed to remove electrons.

Answer 4

Electron is bound in the system of atom  and the total energy of nucleus-electron system is -ve thats why it need some +ve evergy(to be absorbed) in the system  thats why...

energy is absorbed

Answer 5

Work has to be done to remove the electron from the attraction of the protons in the nucleus.  This requires an input of energy: so the process is endothermic
