Verified step by step guidance1
Understand the basic structure of a carbon atom: Carbon has an atomic number of 6, which means it has 6 electrons. These electrons are arranged in two energy levels: the first level holds 2 electrons, and the second level holds 4 electrons.
Recognize the concept of valence electrons: The electrons in the outermost shell of an atom are called valence electrons. Carbon has 4 valence electrons in its outer shell.
Learn about the octet rule: Atoms tend to form bonds in such a way that they have 8 electrons in their valence shell, achieving a stable electron configuration similar to noble gases.
Determine the bonding capacity of carbon: Since carbon has 4 valence electrons, it can form 4 covalent bonds with other atoms to satisfy the octet rule.
Conclude the number of independent molecules carbon can bind: Given that carbon can form 4 covalent bonds, it can bind with 4 independent molecules at once, assuming each bond is with a different molecule.
