Caculate the energyassociatedwith the firstorbitof He^(+).What isthe r

1.	Caculate the energyassociatedwith the firstorbitof He^(+).What isthe radiusof thisorbit ?
Answer» SOLUTION :Electionconfigurationof `He^(+)= 1s^(1)` ENERGYOF `N^(TH)`orbitpossessingone `vec ( e)= E_(B)` for`He^(+)=n =1` andz=2 Theradiusof theorbitr=` ((0.0529 nm) n^(2))/( Z)` for `He^(+)` so`1s^(1) ` and `n=1z=2 ` `r_(1) = (0.0529 nm (1)^(2))/( 2 )` `=0.0264 nm` `52.9pm = 0.0529` nm `1PM= 10^(3) nm`
