The Schrddot(o)dinger equation has been solved exactly only for
(i) `H` (ii) `He^(+)`
(iii) `Li^(2+)` (iv) `b^(3+)`

Options

A. `(i),(ii),(iii),(iv)`
B. `(ii),(iii),(iv)`
C. `(i),(ii),(iii)`
D. `(i),(ii),(iv)`

Answer

C

Explanation

It is solved exactly only for one-electron species. Simplifying assumptions are necessary to solve the equation for more complex atoms and molecular. However, scientists have used their intuition, ingenuity, and modern computers to apply this equation to more complex sysytem.
