(a)
Interpretation:
Whether carbon-13 is radioactive or stable has to be discussed.
Concept Introduction:
Radioisotopes are isotopes of an element having an unstable nucleus and dissipate energy in the form radiation in order to stabilize the nucleus.
(b)
Interpretation:
Presence of various isotopes in food has to discussed based on the analysis of hair sample.
Concept Introduction:
Isotopes are elements that have same atomic number but different mass number.
Radioisotopes are isotopes of an element having an unstable nucleus and dissipate energy in the form radiation in order to stabilize the nucleus.

- 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.
