Regarding carbon, which of the following statements is true?
Carbon is trivalent.
Carbon is tetravalent.
Carbon is bivalent.
Carbon is monovalent.
Carbon is tetravalent.
Carbon is a tetravalent element, meaning it has a valency of 4 because its electronic configuration is 2,4 and it has 4 valence electrons in its outermost shell. To achieve a stable noble gas configuration, it shares these four electrons with other atoms, forming four covalent bonds.
Carbon is a tetravalent element, meaning it has a valency of 4 because its electronic configuration is 2,4 and it has 4 valence electrons in its outermost shell. To achieve a stable noble gas configuration, it shares these four electrons with other atoms, forming four covalent bonds.
Think of carbon as a 4-handed builder who can hold hands with up to 4 other friends simultaneously to construct complex structures like organic molecules.
C-4: Carbon is tetravalent (Tetra = 4).
Atomic┬аNumber┬аof┬аCarbon┬а(Z)=6
Electronic┬аConfiguration=2,4
Carbon has an atomic number of 6. Its electrons are distributed as 2 in the K-shell and 4 in the L-shell. Since it has 4 valence electrons, it cannot easily lose four electrons (requires huge energy) or gain four electrons (energy-unfavorable for the small nucleus to hold 10 electrons), so it achieves stability by sharing four electron pairs, exhibiting tetravalency.
Carbon belongs to Group 14 of the periodic table.
It possesses 4 valence electrons in its outermost shell.
Carbon exhibits tetravalency and forms strong covalent bonds.
Due to tetravalency and catenation, carbon forms a vast number of organic compounds.
Allows formation of stable chains, branched structures, and rings (catenation).
Enables single, double, and triple covalent bonds.
Basis of all organic chemistry and life biochemistry.
Manufacture of polymers, pharmaceuticals, and petrochemicals.
Option A is incorrect because carbon is not trivalent.
Option B is correct because carbon's valency is 4 (tetravalent).
Option C is incorrect because carbon is not bivalent.
Option D is incorrect because carbon is not monovalent.
B is correct тАФ Carbon is tetravalent.
Remember that elements in Group 14 like Carbon and Silicon have 4 valence electrons, making them tetravalent and foundational for organic chemistry and semiconductor electronics respectively.
