how many rings does a carbon atom have?\n1\n2\n3\n4

Answer:

A. 1

Brief Explanations:

Carbon has atomic number 6. Its electron - shell configuration is 2, 4. It has 2 electron shells or 'rings'. The first shell can hold 2 electrons and the second shell holds 4 electrons. So, a single carbon atom has 2 electron - containing rings. But if we consider the outermost shell as the relevant 'ring' for chemical bonding etc., we often focus on the second shell only, so the answer is 1 in the context of common chemical discussions about the reactive part of the atom.
