From her answers, i could see that she really did put effort and it is really detailed. The pictures were big and clear for us to see. However, for Question 2, her drawing for sodium ion's charges was wrong. It should be '+' and not '1+'.

The answers provided by Shuyu is very detailed and clear. She even provided picture for us to understand better and she changed her words colour to bright colour for us to read clearly. I think that she could write the maximum number for each shell like what she did in Question 2 and 3 for Question 1.

Her answers were short but straight to the point. I can see that she put effort in her wok and searching for pictures. But i hoped that she would be more detail and her sulfur ion does not the bracket and charges.
