Which statement is false about the Born-Haber cycle?

a. The value for the conversion of a gaseous metal atom to its ion/s comes from the metal's ionisation energy/energies.

b. The gaining of an electron by the non-metal is often a reaction that requires energy (positive energy value).

c. The value for the conversion of a gaseous non-metal molecule to its atom/s some from the non-metal's bond energy.

d. The final compound formed has the lowest energy level of all the precursor atoms and elements.

Which of the below is not a rule for linear combination of atomic orbitals?

a.

Molecular orbitals can only form if the atomic orbitals have the appropriate shape and orientation in space.

b.

Molecular orbitals can only form if there is sufficient and significant overlap of the atomic orbitals.

c.

Molecular orbitals can only form if the atomic orbitals involved have same or relatively close energy.

d.

For every bonding molecular orbital that forms, there will be an antibonding and a non-bonding molecular orbital.

Which of the below statements are true about the Born-Haber cycle?

a.

Is drawn in a square/circle to depict the cyclical nature of the reactions.

b.

The energy of the reaction of gaseous atoms to form an ionic lattice is called the lattice enthalpy.

c.

All the values in the cycle when added in the same direction sum up to give a value of 0.

d.

Starts at the highest energy level then keeps progressing down to the lowest energy level.
