No to both.
A molecule is not an unique entity. It is common to any substance. Any no. of atom which combine together by chemical bonds form a molecule. The melting point of any molecule depends upon its chemical composition.
The energy stored in chemical composition is known as chemical energy. It is the potential energy stored in the bonds between atoms within a molecule. This energy can be released or absorbed during chemical reactions.
In chemical bonds In chemical bonds
A molecule contain chemical elements associated by chemical bonds.
A molecule stores its potential energy in the arrangement of its atoms and the chemical bonds between them. Energy is released or absorbed during chemical reactions when these bonds are broken or formed, respectively.
A chemical molecule
The existing chemical bonds break and new bonds are created to give products.
Molecule
Atoms in a molecule stay together through chemical bonds, which are formed by the sharing or transfer of electrons between the atoms. This creates a stable arrangement of atoms in the molecule, known as a molecular structure. The type and strength of the bonds depend on the types of atoms involved and their arrangement in the molecule.
undergoes a chemical reaction, resulting in the formation of new substances with different chemical properties. This usually involves a rearrangement of atoms and the breaking and forming of chemical bonds, leading to a change in the composition and structure of the material. In contrast, physical changes only affect the physical state or appearance of a substance without altering its chemical composition.
They are covalent bonds.
