Interpretation:
Difference between metal and non-metal has to be state.
Concept Introduction:
Periodic table is a chart in which the element with similar physical and chemical properties are grouped together. The horizontal rows are called groups based on their chemical property. The elements are classified into three types are metals, non-metals and metalloids. Metals are conductor, non-metals are semi-conductor and metalloid has the property of both metal and non-metals. The elements often referred by group numbers (group 1A, 2A and so on). The group 1A elements are called alkali metals, group 2A metals are called alkaline earth metals, group 7A metals are called noble gases and group 8A elements called noble gases.

- I'm having trouble with converting lewis diagrams into VSEPR diagrams. I currently have this example of C2BrCl3 which I want to turn into a lewis structure, but I'm not sure what steps I need to do in order to do so. I have the table written down, however, there's two central atoms so what would I do? There seems to be 4 electron domains on the carbon atom and no lone pairs so it would seem like this shape would be tetrahedral. Here's what I have now.
