If the 3d and 4s bands overlap in a metal atom, what is the maximum number of electrons for this composite band? express your answer numerically as an integer.

Hey there!

3d band can hold as many as 10 electrons, while 4s can bear as many as two electrons.

The maximum number of electrons for this composite band should be 12 electrons.

Hope that helps!

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
