Sunday, July 3, 2011. The points are very detail and image are very clear and easy to understand too! I think it is very good to highlight the keywords, i should also do so the next time round! For question 2 and 3 she even include the point that "losing 6 electron is difficult.& gaining 7 elecrons is difficult. respectively.", which very few people do so. I think it is good that she include this point which make us understand even clearer. The blogskin is very nice! She put in effort doing it too!

Her answers are very clear and easy to understand, she even take the effort to make a range of colours for the questions and answers which make it even neater and easy to read. But i think it would be better if she show the working of how she obtain the ionic equations. Great effort as well! She put in effort doing it too!
