Solution

To determine the correct atomic symbols for the given elements—carbon, calcium, copper, and cobalt—we need to know their accepted chemical symbols:

  1. Carbon: C
  2. Calcium: Ca
  3. Copper: Cu
  4. Cobalt: Co

Now, let's match these symbols with the options provided:

a) C, Cu, Ca, Co
b) C, Ca, Co, Cu
c) C, Ca, Cu, Co
d) Ca, C, Cu, Co

Verifying Options

  • a) This option lists Carbon (C) first, followed by Copper (Cu), Calcium (Ca), and Cobalt (Co). However, this is not the correct order where Calcium should come after Carbon.
  • b) This option correctly places Carbon first, followed by Calcium, then Cobalt, and finally Copper, but it doesn't list them in conventional order.
  • c) This option lists Carbon (C) first, followed by Calcium (Ca), Copper (Cu), and Cobalt (Co). This is a valid and clear arrangement where Carbon comes first, followed by Calcium, and then the transition to the transition metals, copper, and cobalt.
  • d) This option starts with Calcium, which is incorrect as Carbon should be the first.

Conclusion

The best representation of the correct atomic symbols is found in option c) C, Ca, Cu, Co.

Final Answer

c) C, Ca, Cu, Co
