1. An orbit is a well-defined circular path followed by electron around nucleus.
2. Atomic orbitals are regions of space around the nucleus of an atom where an electron is likely to be found.
3. Electronic configuration is the arrangement of electrons in the orbitals of an atom or molecule.
4. Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals which are equivalent (same in energy).
5. Chemical bond refers to the forces of attraction holding atoms together to form molecules.
6. Bond fission is the breaking of chemical bonds.
7. Free radicals are uncharged molecules or atoms having an unpaired valence electron. They are typically highly reactive and short-lived.
8. Bond energy (E) is the amount of energy required to break apart a mole of molecules into its component atoms. It is a measure of the strength of a chemical bond.
9. Chemical reaction is a process in which one or more substances (the reactants) are converted to one or more different substances, (the products). It involves bond breaking and bond making.
10. Energy of activation (Ea) is the minimum energy required to start a chemical reaction. The activation energy of a reaction is usually denoted by Ea and is expressed as kilojoules per mole (kJ/mol) or rarely kilocalories per mole (kcal/mol).
