The force that holds two atoms together is called a(n) chemical bond. Bond energy is a measure of the strength of a chemical bond. When atoms rearrange to form new combinations, a(n) chemical reaction. has taken place. Such changes generally involve electrons in the highest principle energy level, or the . …

Chemistry: The basis for life. ... Two or more atoms can combine chemically and form a MOLECULE. A COMPOUND is any pure substance that contains two or more different atoms. i.e. Atom = H Molecule = H2 Compound = H2O. Atoms, elements and compounds are forms of matter. Matter can come in one of three states on the earth.

Notes. It's important to know that many chemical reactions are reversible. That is: For example, under certain conditions, one mole of the colourless gas N2O4 will decompose to form two moles of . brown NO2 gas: N2O4 ( 2 NO2. colourless brown. Under other conditions, you can take 2 moles of brown NO2 gas and change it into one mole of N2O4 gas:

Covalent bonds can form between atoms of the same element or atoms of different elements. While both types are molecules, the latter are also compounds. Water, H2O, is a compound in which two H atoms form single covalent bonds with an O atom. This satisfies the valences of both elements. Methane, CH4, satisfies the valences of both C and H.

Only non-metals are able to be seen in this diatomic state in nature. This is because metals will usually form oxides or will be in a large metallic or lattical structure which consists of millions of atoms infinitely bonded. Other elements may form compounds which contain two or more different elements in each compound. For example H2O.
