Text Solution

Verified by Experts

`He^+ (g) rarr He^(2+) (g) +e`
` :. E_1 "for" He^+ =- 2. 18 xx 10 ^(-18) xx Z^2`
` =- 2. 18 xx 10^(-18) xx 4 =- 8. 72 xx 10^(-18) J`
`:.` Energy required for the ionisation of `He^+`
` = 8. 72 xx 10^(-18) J`,

The energy needed for Li_(g) rarr Li_(g)^(3+) + 3e is 1. 96 xx 10^4 kJ mol ^(-1) . If the first ionisation energy of Li is 520 k J mol^(-1) . Calcuate the second ionisation energy of Li . (Given : IE_1 for H = 2 . 2. 18 xx 10^(-18) k J "atom"^(-1) ).

A quantitative measure of the tendency of an element to lose electron is given by its ionization enthalpy. It represents the energy required to remove an electron from an isolated gaseous atom (X) in its ground state. In other words, the first ionization enthalpy for an element X is the enthalpy change (Delta_(i)H) for the reaction depicted. X(g) rarr X^(+) (g)+e^(-) The ionization enthalpy is expressed in units of kJ mol^(-1) . We can define the second ionization enthalpy as the energy required to remove the second most loosely bound electron: it is the energy required to carry out the reaction, X^(+)(g) rarr X^(2+)(g) +e^(-) Consider following statements for the two uncharged gaseous species Species -1 =1s^(2),2s^(1) Species -2 =1s^(2),2p^(1) (P) Species-1 is ground state, species-2 is excited state of same atom (Q) Species-1 is excited state, species-2 is ground state of same atom (R) Ionization of species-1 is easier as compared to species-2 (S) Ionization of species-2 is easier as compared to species-1 Select correct statement(s)
