COMMENTS ON THREE OTHER FRIENDS' BLOG 1) Aleen (27)Answers are detailed and well written. Pictures were drawn neatly and clearly .There are some spelling mistakes like 'moer' in question 2 . Some pictures were found in google and uploaded as well for our reference. For question 1 , she could draw a atom to show how does a atom looks like. I like her answer for question 5 as she gave some extra infomation about other metals and non-metals, like water and lemon which is a non-metal conduct electricity. Blog is nicely done and there is even music for us to listen while we are reading her answer.
2) Shu Yu (12)Answers are simple and easy to understand. Pictures were taken and uploaded. Some spelling mistakes like "ocnfiguration". For question 1 , maybe she can elaborate more about the sub-atomic. I like the way she did question 5. She listed it down in point form. It is easier to see the important points. She listed down the chemical properties and physical properties of metal and non-metal .Blog is nicely done too.
3) Wan Ling (16)Answers are easy to understand. Not too wordy. Pictures are clear and nice. For questions 2 and 3 , she could have drawn the atoms and ions to show that she understand how to draw it. For question 3 , the sulfur ion, it should have brackets and the 2- should be outside the bracket instead of inside the circle . I think she did a good job on question 1. I like the part where she wrote this "Mass number/ Nucleon number/ Ar (relative atomic mass) : protons = neutrons Proton number=Atomic number No. of electrons=No. of protons No. of neutrons=Nucleon number-no. of protons" its is very detailed and very easy to understand. The pictures taken from websites can be as a reference . Blog is nicely done.
