He2+ Bond Order

What is the sequence of He2 + bonds according to molecular orbital theory? 3

a) 0

b) 0.5

C) 1

d) 1.5

e) 2

Please help me I'm really lost I give 5 points for the best answer.

Since He2 + is isoelectronic for H2 (i.e. it has the same number of electrons and the same structure if the atom number em is ignored), its bonding order is the same as H2, which is 1 (you know) Is H included in H, of course just a link?)

Specifically, two ■■■■ agents (one in each helium atom) combine to form a low-binding ■■■■ agent and a high-energy ■■■■ anti-binding agent. Since species have only two electrons in total, they can form an ■■■■ bond. The number of bond order bonding electrons is the number of minus anti-bonding electrons, all 2, ie (20) / 2 = 1.

I just took the test online. I chose 1 that the user saw, but it was wrong. That is the correct answer.

According to ■■■■ molecular theory, what is the sequence of bonds for He2 +?

the answer:

A.1.5

B.0.5 (True)

Vs. 1

D.2

(2 electrons in bonding pair 1 conductor pair) / 2 = 0.5
