When atoms bond together, they form molecules or compounds to achieve stable electron configurations. A chemical equation is a symbolic representation of a chemical reaction, showing the reactants on the left and products on the right. For an equation to be balanced, it must satisfy the law of conservation of mass by having the same number and type of atoms on both sides.

3. All matter is made of atoms. Why would an atom combine with other atoms? To make the atom stable When an atom combines with another atom, this forms a molecule? The other type of bond is a compound.

5. A chemical equation is a symbolic representation of a chemical reaction .

6. Equation Example : The burning of methane gas in oxygen is: CH 4 + 2 O 2 -> CO 2 + 2 H 2 O
