The energy required to completely dissociate two atoms that are covalently boned together is called?

The energy needed to break a bond between two atoms is the called the bond energy. The SI units for bond energy are kJ/mol.


What are bond energies and how do they relate to stability of a bond?

individual atom is unstable because of its high energy, so through bonding it shares its energy with other atom and as a result both get stable. we can also explain this fact by octet rule, if the outermost shell of an atom is not complete that means atom is not stable. so to make that stable it will make a bond with another unstable atom as a result of sharing or transfer of electrons BOTH WILL GET STABILIZE...........

What happens when two atoms absorb thermal energy when joining together to form a molecule?

That energy is trapped in the bond. The bond energy is called bond enthalpy and is available in tables on the internet. Energy is required to break a bond but released when bonds form. If the sum of the reactant bond energy is less than the sum of the product bond energy then energy will be released in the chemical reaction.


How is the stregth of a covalent bond related to its bond dissociation energy?

The strength of the bond increases as the bond dissociation energy increases.
