Question

DEFINE IE1 AND IE2 . WHY IS IE2>IE1 FOR A GIVEN ATOM?DISCUSS THE FACTORS THAT EFFECT IE OF AN ELEMENT​

Answer 1

Answer:

ionisation energy or Ionisation enthalpy is the enrgy required to remove the most loosely bound electron from an isolated gaseous atom and IE1, IE2, these are the removal of first as well as second electron from an atomThe notation that you have given is wrong, the second ionisation energy is always more than that of ...

Ionisation energy or ionisation enthalpy is the enrgy required to remove the most loosely bound electron from an isolated gaseous atom and IE1, IE2, these are the removal of first as well as second electron from an atom and the notation that u have given is wrong, the second ionisation energy is always more than that of first ionisation energy.

Beacuse, once a atom looses one electron, then it will trying to make it more stable, so, the force that nucleaus exert on outer shell electron will be increased, in that case we have to apply more force for removing the 2nd electron.

Factors affecting IE:-

• Atomic radius
• Nuclear charge
• Orbital penetration
• Sheilding or screening effect
• Electron pairing within a subshell
