Final answer:
The valence value of carbon is 4. This indicates that carbon, which is in group 14 of the periodic table, has 4 valence electrons. This means that it can form four bonds with other elements or compounds.
Step-by-step explanation:
The question asked is: What is the carbon valence value? The valence value of an element refers to the number of electrons it can share, borrow, or donate during a chemical reaction. In the case of carbon, it is located in group 14 (or IVa) of the periodic table. This means it has 4 valence electrons as it exists naturally and can form four bonds with other elements or compounds. So, the correct answer is D) 4
Evidence of this is found in several compounds. For instance, in a molecule of CH4 (methane), each of the hydrogen atoms (Group 1) has 1 valence electron, and the carbon atom has 4, for a total of 8 valence electrons in the molecule. These valence electrons form the bonds between atoms.
