Energy required to ionise 2 mole of gaseous `He^(+)` ion present in its ground state is :

Energy required to ionise 1 mole of gaseous He^+ion present in its ground state is

The amount of energy required to remove the electron from a Li^(+2) ion in its ground state is x times that of the amount of energy required to remove the electron from an H-atom in its ground state find .x.

The amount of energy required to remove the electron from a Li^(2+) ion in its ground state is how many times greater than the amount of energy required to remove the electron from an H atom in its ground state:

The energy required to remove an electron from a gaseous atom from its ground state is called

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 enthalpy of lithium is 520 kJ*mol^(-1) . The amount of energy required to convert 210 mg of Li-atoms is gaseous state into Li^(+) ions is-
