When you join one atom of hydrogen and one atom of helium, you get a molecule with the chemical formula HHe. This is not a stable combination as the resulting molecule is highly reactive due to the different properties of hydrogen and helium atoms.
The five characteristic properties of matter are mass, volume, density, shape, and texture. These properties help define the physical and chemical nature of different substances and can be used to distinguish one from another.

Minerals are classified by chemical formula, composition, physical properties, optical properties, and special properties. The Dana Classification System is a chemical classification for minerals, and the Strunz Classification System (chemical-structural) are two systems designed for mineral classification.

Change in temperature, gaseous bubbles, giving off light, change in color, change in properties. These are chemical changes, but it is still five examples of science.
Helium, boron, oxygen, fluorine, iodine.
Hydrogen, Helium, Carbon, Gold, Silver, Oxygen
- chemical reactivity - thermal stability - flammability - oxydation - reduction

It is supposed that bohrium has chemical properties similar to the properties of his homologue, rhenium. Only the compound BhO3Cl is known today. The predicted valences of bohrium are 7, 5, 4, 3.
Some examples of the properties of multiplication are the idenity property are EX./ 5*1=5 Then there is the associative property. EX./ 7*(5*6)=5*(6*7) Communative property EX./5*4=4*5 zero property EX./ 5*0=0

Physical properties: Color - the visual appearance of a substance. Density - the mass of a substance per unit volume. Melting point - the temperature at which a solid changes into a liquid. Hardness - the resistance of a material to deformation. Conductivity - the ability of a material to conduct electricity or heat. Chemical properties: Reactivity - how readily a substance undergoes a chemical reaction. Flammability - ability of a substance to burn in the presence of oxygen. Toxicity - the harmful effects of a substance on living organisms. pH - a measure of the acidity or alkalinity of a substance. Oxidation state - the readiness of an element to gain or lose electrons in a chemical reaction.
