The energy required to remove an electron from an isolated gaseous atom in its ground state is called ionisation enthalpy.From the following, select the element having maximum value of 2^(nd) ionization enthalpy. Be C N O

" How many unpaired electrons are present in a gaseous \(Co^{+3}\) ion in its ground state? "

The ionisation energy (IE_(1)) of an atom is defined as the energy needed to remove an electron from gaseous atom in its ground state. The 2nd ionisation energy (IE_(2)) is the additional energy needed to remove the 2nd electron and so on. The successive ionisation energy of any species is increasing always. Generally, the first ionisation energy increase along a period. But there are some exceptions. One which is not an exception is:
