define ie1 and ie2 why is ie2 greater than ie1 for a given atom discuss the factors that
effect ie of an atom
Answers
Answer:
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 atom . ... the second ionisation energy is always more than that of first ionisation energy .
Answer:
First Ionization energy is the energy required to remove the outermost electron.
Second Ionization energy is the energy required to remove the second electron.
Explanation:
IE2 is greater than IE1 because after losing an electron, size of atom decreases and the gripping force on the remaining electrons gets stronger and it needs higher energy to remove the second electron.
IE decreases when size of atom increases and vice-versa. IE is higher for cations because of smaller atomic radius.
