The amount of energy required to remove an electron from the last orbit of an isolated (free) atom in gaseous state is known as ionization potential or first ionization potential of the element. Similarly, the energy required for the removal of the electron from the unipositive ion (produced above) is referred to as second ionization potential and thus the third, fourth etc. lonization potentials may be defined in general as the number of ionization potentials of an element may be as much as its number of electrons. Which of the following statemetn is correct ?

1.	The amount of energy required to remove an electron from the last orbit of an isolated (free) atom in gaseous state is known as ionization potential or first ionization potential of the element. Similarly, the energy required for the removal of the electron from the unipositive ion (produced above) is referred to as second ionization potential and thus the third, fourth etc. lonization potentials may be defined in general as the number of ionization potentials of an element may be as much as its number of electrons. Which of the following statemetn is correct ?
Answer» IE of elemnts increase along the period IE of the `3^(rd)` GROUP elements is less than that of the SECOND group elements. IE of group 16 element is less than that of group 15 elements. All of the above Answer :D
