The ammount of enrgy requred to remove the electron from a `Li^(2+)` ion in its grojnd state is , how many times greater than the amount of enrgy reuired to remove the elrcton firm an H-atom in its grojn state ?

A

`9`

B

`2`

C

`3`

D

`5`

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(Li^(2+)) = E_(H) xx Z^(2)`
` thereforeE_(1 Li^(2+))/E_(1H) = Z^(2) = 3^(2) =9`.

A hydrogen-like atom in its first excited state has excitation energy of 91.8 eV. The energy required to remove the electron from its ion is:

The energy required to remove an electron from the outermost shell of an isolate gaseous atom is known as IE_(1) of that atom. Similarly, the enrgy required for the removal of the electron from the unipositive ion, diapositive ion and tripositive ion are known as IE_(2),IE_(3) and IE_(4) respectively, and are called successive ionisation energies. The magnitude of the charge depends on the size of the orbital of electron. Electrons in smaller orbitals are on average close with each other and have more repulsion. Thus for Be(2s^(2)) , the IE_(1) and IE_(2) are 9.3 and 18.2 eV "atom"^(1) , whereas for Ca(4s^(2)) , the values are 6.1 and 11.9 eV . Consider the IE_(1) of the element whose electronic configuration correspond to the following:
