One can think of the kinetic energy of a particular electron of an atom as an inverse function of its confinement. In other words, it is a lower energy state for an electron to be de-localized over a larger area. By forming a bond, an electron essentially occupies twice as much space as it did previously. This is lower energy.
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.
no, some reactions are spontenous.
It requires energy.

When substances change state, energy is either absorbed or released. During melting and boiling, energy is absorbed to break the intermolecular forces holding the substance together, while during freezing and condensation, energy is released as these forces are formed. This energy change is due to the breaking or forming of bonds between molecules.

The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.
Chemical changes involve breaking and forming of bonds between atoms. Chemical energy is required to break bonds. The formation of new bonds releases energy.
The enthalpy change associated with a reaction = sum of (energies of bonds broken) - sum of (energies of bonds formed). Thus, if this value is net negative, the reaction is exothermic; the products are also more stable than the reactants (lower-energy bonds). A positive enthalpy indicates an endothermic reaction.
Forming chemical bonds releases energy because it involves a decrease in potential energy as atoms move closer together to form more stable configurations. Breaking bonds, on the other hand, requires energy input to overcome the attraction between atoms.
no, some reactions are spontenous.
Mechanical energy is involved when breaking sticks, as the force is applied to overcome the internal forces holding the stick together. This mechanical energy is converted into kinetic and potential energy as the stick breaks.
Yes, reactions typically involve a transfer of energy between molecules. This transfer can result in breaking or forming chemical bonds, leading to changes in the energy of the system. Whether energy is absorbed or released depends on the specific reaction and its thermodynamic properties.
Forming bonds releases energy because when atoms come together to form a bond, they are able to achieve a more stable and lower energy state than when they are separate. This release of energy is due to the attraction between the positively charged nuclei and the negatively charged electrons in the bond, which results in a more stable configuration for the atoms involved.
Chemical reactions weaken bonds by absorbing energy to break them, and release energy when forming new bonds. This process involves breaking existing chemical bonds through input of energy, and then forming new bonds that release energy. This cycle of bond breaking and bond formation allows for energy to be absorbed and released in a controlled manner.
