Question

what information would you use to support the view that the molecule of he²does not exists

Answer 1

[tANSWER

Electronic configuration of He is 1s2.

Molecular Orbital Diagram for He2 is

(Refer to Image)

Bond order= 2(No. of electrons in bonding molecular orbital)-(No. of electrons in anti-bonding Molecular orbital)

                    =22−2=0

∴He2 bond order is 0. There is no bond existing between atoms of He2. So He2 does not exist.

Answer 2

Electronic configuration of He is 1s²

Molecular Orbital Diagram for He2 is(Refer to Image)

Bond order=

No. of electrons in bonding molecular orbital)-(No. of electrons in anti-bonding Molecular orbital)/2

=2−2/2

=0

hope it HELPS you
