<h2>What is chemical binding?</h2>
Chemical bonding helps to joining atoms or molecules together. It is also helps molecules of the same or different substance to get together through joining to each other . Solid , liquid, or gaseous matter can exist in the nature due to chemical bonding .
<h3>How Chemical bonds are formed?</h3>
Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions. Valence electrons are the basis of all chemical bonds.
There are two primary kinds of chemical bonds that keep atoms together:
- Covalent
- Electrovalent/ionic bonds.
Covalent bonds have atoms which share electrons in a chemical bond.
Ionic bonds are formed by the of atoms that have opposite charges
- Sodium chloride, or NaCl, is an example of an ionic bond.
- Another example of an ionic bond is found in lithium fluoride (LiF). Lithium has one electron in its outer shell, and fluorine has seven electrons in its outer shell.

Answer: 
Explanation
Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced combustion reaction for butane is,:
The first 92 elements of the periodic table are naturally occurring elements.
