Answer:
B
Explanation:
Carbon is an element with an atomic number 6, the electron configuration is 2,4. This means it has four electrons in its outer-most shell or valence shell. The valence shell needs 8 electrons to be filled. Thus the outer electron shell of carbon is unfilled.
It reacts with other elements covalently and forms organic and in-organic compounds.
The 4 electrons in the valance shell of carbon makes it a metalliod, but commonly its considered as a non-metal.
However carbon can form single and double covalent bonds. It forms single covalent bond when it combines with 4 atoms of Hydrogen in the methane molecule
