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.

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
