6)

For copper atom and the copper(I) ion:

Draw and label the complete atomic orbital energy level diagrams with the correct amount of electrons as we learned to do in class. Remember to label your diagrams with which way the energy increases and label the orbitals.

Then on the diagram for the atom, circle the valence electrons.

Finally, tell if the atom is paramagnetic or diamagnetic and if the ion is paramagnetic or diamagnetic.

Time: 1 hour, 48 minutes, 19 Quesson Completion Status: QUESTION 5 Which of the waves pictured below has the alower o wave A wave neither or both same QUESTION 6 Based off of the diagram below. the wave Draw the lines alphabeticaly or will be maned wrong. B. QUESTION 7 A A A A labels amplitude of the wave, the 0.5 points 1.5 points 3 points

Explanation / Answer

Ans 5 c neither or both same

We can see that both waves are travelling the same distance in given period of time so both of them have the same velocity, though the frequency of wave b is more, but that does not contribute to any change in its velocity.
