I need answers for these.

Why do you need TSR? These are just recall questions, look at your textbook

Could you give me an Idea of what topic these questions might be under?

2a. https://www.google.com/search?q=ions+in+sodium+chloride&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjIs-yMjJrcAhVOMewKHcv3BkMQ_AUICigB&biw=1280&bih=726#imgrc=i2rnfQfsLSlH0M:

b. ionic bonds

c. Mg2+ and 02- have a greater charge than Na+ and Cl-

3.

a + b. For diamond and graphite: http://igcse-chemistry-edexcel.blogspot.com/2015/12/144-draw-diagrams-representing.html

c. Diamond is made of carbon atoms that form a tetrahedral arrangement. In diamond, one carbon atom binds 4 other carbon atoms via covalent bonds. In graphite. one carbon atom binds 3 other carbon atoms via covalent bonds. Also, graphite forms these type of weak intermolecular forces which are not covalent between its layers. Therefore, graphite can be molded and diamond cannot.

Hope that helps.
