Chemical formulas are named based on the number and type of atoms in the chemical. In chemical formulas of two atoms with opposite charges, the first element is a metal and the second is a non-metal. The chemical's name is the name of the metal and the name of the non-metal, with the non-metal's nam
Examples of chemical formulas of compounds are HBr for hydrogen bromide, NaClO for sodium hypochlorite, NaOH for sodium hydroxide and NaCl for sodium chloride. Some chemical symbols for elements include H for hydrogen, C for carbon, Ti for Titanium, Sn for tin and I for Iodine.
The chemical formula for water is H2O. A molecule of water consists of two hydrogen atom that bond with one atom of oxygen. The hydrogen and oxygen atoms share electrons because they are covalently bonded.
Since lead is an element, it does not have a chemical formula; however, its chemical symbol is Pb. Lead is found in group 14 on the periodic table. Its atomic number is 82 and atomic weight is 207.2.
Milk is a complex solution composed of water, solids, fat, proteins, lactose and minerals. Many of these components are compounds on their own, giving milk its very complicated chemical makeup.
The main functional group of alcohols is the hydroxyl group, written as "-OH". There are many different types of alcohol and molecular formulas vary based on the number of carbon atoms and the placement of the –OH group in the molecule.
Ice is the solid form of water that is created when water freezes at a temperature of zero degrees Celsius, so it has the same chemical formula of water, which is H2O. Water consists of two atoms of hydrogen and one atom of oxygen.
Because an egg is an entire biological structure, made up of a mixture of chemicals rather than a single pure chemical compound, there is no one chemical formula to describe it. However, the basic structure and chemistry of an egg is highly conserved and varies little from species to species.
The chemical formula for most glass is SiO2. Commonly referred to as sand, it's the main ingredient in the most common forms of glass.
According to the National Center for Biotechnology Information, the chemical formula for oxygen is O2. The O stands for the oxygen molecule, while the 2 represents the need for two oxygen molecules to form the element.
