Question

which homonuclear molecules of the second period should have zero bond order​

Answer 1

Answer:

The Li atom four electrons in bonding orbital and two electrons available in antibonding electron so it bond order is one. Bond order of Be2molecule is zero hence, the molecule don't exist.

Answer 2

The homo nuclear molecules of Lithium and Berilium in the second period will have zero bond order.

Explanation:

• Homonulcear molecules are those molecules which are composed on only one type of element.
• In the case of Lithium and Berlium elements, the presence of homonuclear molecules are high and hence they have zero bond order.
• These elements which forms the zero bond order of the periodic table have their molecules in a more unstable state in such a way that they even don't have the capacity to exist
