The bond order =
The electron configuration is (1s)2 (*1s)2 (2s)2
Formation of Be2
Is it possible to form Be2?
We dont have Be2 because bond order will be equal to zero
Molecular orbitals for p orbitals
Since there are three 2p orbitals, we can ex
The effect of pressure and temperature on physical state of a compound can be presented in a phase diagram.
It is important to know that the diagrams are not drawn to scale.
