Which statement is true about carbon? A) It shares its valence electrons. B) It has two valence electrons. C) It is non-reactive. D) It is a metal.

The correct answer is A.

Explanation:

Carbon shares the electrons in its valence layers. For example, a carbon-oxygen bond is a covalent bond between a carbon atom and an oxygen atom and is one of the most abundant found in nature. Being covalent means that they share electrons between their atoms.

The elements of the second period have their valence electrons in orbitals 2s and 2p. Therefore carbon has 4 valence electrons. It should also be noted that it is an element belonging to non-metals.

Have a nice day!
