Which statement correctly describes an electrode in a voltaic cell of copper and hydrogen?

a. copper atoms become copper ions at the anode because the srp is more positive.

b. hydrogen ions become diatomic hydrogen at the cathode because hydrogen is always reduced in a voltaic cell.

c. copper ions become copper atoms at the cathode because copper is always reduced in a voltaic cell.

d. diatomic hydrogen becomes hydrogen ions at the anode because the srp is more negative.

k

explanation:

k

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
