An example of a chemical change occurs when hydrogen combines with oxygen to form a new substance ,water.

An example of physical change in matter would be when water freezes and becomes ice.Its still water but now its a solid instead of a liquid.

The atomic number indicates how many protons are in a single atom of a particular element. For example, the atomic number of hydrogen is 1, which means it has only one proton and 1 electron. Hydrogen is the simplest atomic structure. Carbon has an atomic number of 6 , which means it has 6 protons, 6 neutrons and 6 electrons. Nitrogen has 7, oxygen 8 and sulfur 16.

Molecules are created when two or more elements join together in a chemical bond. For instance, water is a combination of 2 parts hydrogen atoms to 1 part oxygen. Who would have ever thought; water is a "chemical"!

The smallest complete unit of an element is an atom. Atoms are made up of Protons, Neutrons, and Electrons. The atomic number of an element indicates how many Protons are in a single element.

How does matter change from one state to another? Elements and compounds can move from one state to another when specific physical conditions change. For example, when the temperature of a system goes up, the matter in the system becomes more excited and active. If enough energy is pushed into a system, a phase change may occur as the matter moves to a more active state.

Solids, liquids, gases, plasmas, and Bose-Einstein condensates (BEC) are different states of matter that have different physical properties. Solids are often hard, liquids fill containers, and gases surround us in the air. Each of these states is also known as a phase.

Hairs are made of keratin molecules, which contain cysteine. Cysteine has thiol (-SH) group, by which it can form disulfide (-S-S-) bond with another cysteine of another keratin, causing bending of hair. Chemical processes directly effect the disulfide bonds of the hair.

According to Wikipedia, this is a term that describes the forces that include attraction and repulsions between atoms, molecules, and surfaces, as well as other intermolecular forces. In the term of hair, it is what attracts the molecules that make up your hair strands. It is a physical attraction rather than a chemical one.
