The answer is :-
A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.
What is neutralization ?
- neutralization is a chemical reaction where an acid and a base react with each other quantitatively.
- It is also written as neutralization.
- The acid strength of the reactant gives the pH of the neutralization solution.
- When an acid and a base react, the reaction is called a neutralization reaction.
- That's because the reaction produces neutral products. Water is always one product, and a salt is also produced. A salt is a neutral ionic compound.

Explanation:
When there occurs sharing of electrons between two chemically combining atoms then it forms a covalent bond. Generally, a covalent bond is formed between two non-metals.
An ionic bond is defined as the bond formed due to transfer of one or more number of electrons from one atom to another. An ionic bond is always formed between a metal and a non-metal.
Every atom of an element will have orbitals in which electrons are found. These orbitals are known as energy level.
A molecule is defined as the smallest particle present in a substance or atom.
A metallic bond is formed due to mobile valence electrons shared by positive nuclei in a metallic crystal.
Thus, we can conclude that given statements are correctly matched as follows.
1). a chemical bond formed by the electrostatic attraction between ions - ionic bond
2). a chemical bond formed by two electrons that are shared between two atoms - covalent bond
3). the orbitals of an atom where electrons are found - energy level
4). the smallest particle of a covalently bonded substance - molecule
5). a bond characteristic of metals in which mobile valence electrons are shared among positive nuclei in the metallic crystal - metallic bond
This substance is certainly not gas since gas particles have large spaces between them. This substance is certainly not solid as well since solid particles are closely packed together with very close proximity. This substance is therefore liquid since particles are still close but can move around in a disordered arrangement.
