JSS 1: INTRODUCTION TO BASIC CHEMISTRY

-

CHEMISTRY is a branch of pure science that deals with the study of the nature, structure, composition, properties, and uses of matter. The scientist who studies chemistry is called a CHEMIST 

           BRANCHES OF CHEMISTRY 

The four main branches of chemistry are 

1. Physical chemistry 

2. Organic chemistry 

3. Inorganic chemistry

4. Analytical chemistry 

Physical chemistry: deals with the physical aspects of chemistry such as heat, electricity, etc.

Organic chemistry: deals with the study of carbon and its compounds

Inorganic chemistry: deals with the study of elements, their properties, and uses

Analytical chemistry: is a branch of chemistry that focuses on identifying, separating, and quantifying chemical substances. Analytical chemistry is divided into two which are:

(a) Qualitative analysis

(b) Quantitative analysis 

Qualitative analysis:  It is used to determine which substances or ions are present in a chemical substance 

Quantitative analysis: It shows the amount or concentration of a particular substance present in a chemical substance.

REASONS FOR STUDYING CHEMISTRY

The reasons for studying chemistry are: 

1. To acquire knowledge about matter

2. To give training in the scientific method

3. To meet basic needs such as food, clothing, shelter, health, etc

4. To provide solutions to problems

5. To explore new things which are unknown to mankind. 

USES OF CHEMISTRY

Chemistry has contributed greatly toward providing our basic needs and improving the quality of life through: 

1. Provision of food I.e through the use of fertilizer, herbicides, and insecticides in agriculture to boost crop production

2. Provision of clothing with the help of man-made textile fibers.

3. Provision of modern means of transportation

4. Provision of drugs and other medical usages

5. Provision of modern-day housing materials.

6. Provision of military ammunition

7. Provision of knowledge in space science.

DISADVANTAGES OF CHEMISTRY

The disadvantages of chemistry include

1.Rusting

2.Pollution

3.Drug abuse

Assignment 

A. State the uses of the following:

I. Fertilisers 

II. Herbicides 

Insecticide 

Explain the following:

I. Rusting

2. Pollution 

3. Drug abuse

Rusting is also known as corrosion of iron. It is defined as the interaction of Iron with air and water to produce rust.

                              Atom An atom is the smallest particle of an element which can take part in a chemical reaction.                 Components of an atom An atom has two main parts: I. The nucleus (made of proton and neutron) II. The shells (electrons) which surrounds the nucleus at definite distance.                   Structure of an atom                    Sub-particles of an atom An atom is made up of three sub-particles namely: I. Proton II. Electron III. Neutron  Proton and neutron are the nuclear particles found in the nucleus, while the electrons are in constant and continuous motion in the shells at various energy levels around the nucleus.         Characteristics of the sub-particles  ...

                Relative Atomic Mass The Relative Atomic Mass (RAM) of an element is the average mass of its atoms compared with one-twelfth (¹/₁₂) of the mass of one atom of carbon-12. The carbon-12 isotope (¹²C) is used as the standard for measuring atomic masses. Relative atomic mass of an element  = average mass of one atom of element     ¹/₁₂ × the mass one carbon -12 atom                     Relative Moleculer Mass Relative Molecular Mass ( RMM ), also called Molecular Weight, is the sum of the relative atomic masses (RAM) of all the atoms present in a molecule. The RMM has no unit (it’s a ratio). It shows how heavy a molecule is compared to ¹/₁₂  of the mass of one atom of carbon-12 (¹²C). Examples: 1. Water (H=1, O=16)  H₂O = (2 × H) + (1 × O)          = (2 × 1) + (16)        ...
