An ionised H-molecules consists of an electron and wo protons. The protons are seperated by a small distance of the order of angstrom. In the ground state,

A

the electrons would not move iin circular orbits

B

the energy would be `(2)^(4)` times that of a H-atom

C

the electrons, orbits would go around the protons

D

the molecule will soon decay in a proton and a H-atom

Text Solution

Verified by Experts

The correct Answer is:
A, C

The protons are separated by a small distance of the orderf of angstrom. In the ground the electron would not move in circular orbits the electrons, orbit would go around protons.
