Question

What is IE,IE1, IE2.explain​

Answer 1

Explanation:

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

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 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 2ndelectron .FACTORS AFFECTING IE1- atomic radius,2- nuclear charge3- orbital penetration4- sheilding or screening effect5- electron pairing within a subshell .
