Bond Enthalpy (Bond Energy) AP Chemistry

The Bond Enthalpy is the energy required to break a chemical bond. It is usually expressed in units of kJ mol1, measured at 298 K. The exact bond enthalpy of a particular chemical bond depends upon the molecular environment in which the bond exists. Therefore, bond enthalpy values given in chemical data books are averaged values.

Valence Bond Theory | Boundless Chemistry

valence bond theory: a covalent bond forms between the two atoms by the overlap of halffilled valence atomic orbitals from each atom. In chemistry, valence bond (VB) theory is one of two basic theories—along with molecular orbital (MO) theory—that use quantum mechanics to explain chemical .

Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a halflife of about 5,730 years.
