The willingness of the 4f orbitals of lanthanide metals to participate in chemical reactions is as rare as their presence in ...

because no chemical bonds are broken or formed as it takes place. But it generates heat, so can be described as exothermic. Although aqueous solutions of 'slaked' lime are alkaline, its solubility ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...

Bond breaking is an endothermic process. The opposite is true if we want to make new bonds. Energy is released when new chemical bonds are formed, so bond making is an exothermic process.

Electronegativity is crucial for explaining various aspects, ranging from the energy of chemical bonds to the (in)stability of chemical compounds. It is expected to correlate with numerous physical ...
