Chemistry education from A to Z includes a comprehensive overview of what is defined and what is defined in the first place, and then to the later sections and disciplines.
What forms do you have?
1. Pure materials (can be found in the form of elements or compounds)
2. Elements (there are about 90 elements in nature)
3. Vehicles (a substance consisting of a union of two or more elements)
4 - mixtures and solutions.
What are the most important and famous sub-specialties of chemistry?
1- Analytical Chemistry
2. Physical chemistry
3. Organic chemistry ( organic chemistry)
Inorganic chemistry
Biochemistry
What topics should I begin to learn?
Introduction to Chemistry
At the beginning of a chemistry learning trip from scratch, you should take a general look at what this science defines . Why do we need to study and learn chemistry?
2. Units and measurement
You will need to study the International Units System (SI Units); it consists of 7 basic units:
Meter (for measuring lengths)
Kilogram (for mass measurement)
Second (for measuring time)
Amp (to measure the current)
Calvin (for temperature measurement)
Qandila (for measuring the intensity of light)
3. Elements
The material can be divided in several ways according to its composition, behavior, or chemical and physical properties. The most common classification of materials is either an element or a compound. The element is defined as an indivisible chemical into substances that are simpler than chemical reactions and consist of one type of atom.
The element may be present in the form of a single atom such as argon, or in the form of a fraction such as nitrogen (N 2 )
Chemical elements are the basic component of matter, so you will need to learn the following:
How to label chemical elements and what is the symbol used to express each element?
What are the most widespread elements in nature?
How are new chemical elements discovered?
What are the important elements in the composition of the human body?
What are toxic chemical elements?
4. Periodic table
Is a table to arrange chemical elements based on their similar properties. Through this link ( Modern Periodic Table ) you can browse groups and cycles of the periodic table with the possibility to browse the properties of each element on its own.
5 - atoms and ions
The atoms are the structural units of the elements, and the ions are composed of one or more elements and carry an electrical charge.
The human body has about 7 billion billion billion atoms
The most widespread and abundant atom in the universe is the hydrogen atom; it represents approximately 74% of the total atoms in the Milky Way galaxy
Although atoms are the smallest known objects, they are made up of other tiny particles, quarks and leptons, and the latter is closely related to a science called high energy physics or particle physics,
The largest atoms in size are the cesium atom (Cs)
6- Part and compound
The molecule consists of a combination of two or more chemically linked elements; a compound is a molecule containing at least two different elements, so all compounds are molecules and not all particles are compounds. (H2), nitrogen (N 2 ), nitrogen (O 2 ), hydrogen (H 2 ), nitrogen (N 2 ), H 2 O,
7. Chemical equations and reactions
In chemical reactions, reactants bind together and the bonds between their atoms are broken. The atoms are then rearranged to form new chemical bonds to form the products.
8. Atomic structure and electronic distribution
Models and theories proposed to explain the atomic structure, with the identification of the components of the atom (a central nucleus containing "positively charged" protons and neutrons "neutral charge", around which "negatively charged" electrons).
9. Cases of Article
There are four main cases of the article:
Solid State (Solid)
Liquid Condition
Gas
Plasma (Plasma)
There are other cases of the substance but they are not common but only exist in special laboratory conditions such as Bose-Einstein condensates,
10. Chemical links
There are two basic types of chemical bonds (the ionic bond is between two atoms, one is electron donor and the other is electronless; the covalent bond is between two atoms that share equivalence electrons).
What books are proposed on a chemistry trip from scratch?
1. Chemistry for Dummies
2. The Periodic Table: A Very Short Introduction
3. Chemistry: The Central Science
4. Chemistry: Concepts and Problems: A Self-Teaching Guide
What are the branches of advanced chemistry?
There are many sub-sciences that fall under the science of chemistry but are of interest to the specialists in this field first of which, for example:
Polymer Chemistry
Petroleum Chemistry (Petroleum Chemistry)
Environmental Chemistry
Applied Chemistry
Quantum Chemistry
Radiation chemistry ( Radiation chemistry )
Coordinating Chemistry
Pharmaceutical Chemistry
Synthetic Chemistry
Photochemistry
Dyes Chemistry
Industrial Chemistry
Green Chemistry
Corrosion Chemistry
Surface Chemistry & Catalysis
Stereochemistry
Astrochemistry
Cluster Chemistry
Food Chemistry
Medical Chemistry (Medicinal Chemistry)
Nanochemistry
Solid State Chemistry
Forensic Chemistry
Inorganic Chemistry ( Bioinorganic Chemistry )
Some tips and guidance on a chemistry trip from scratch
Interested in mathematics
During your study of chemistry you will be confronted with many formulas and equations that will require a good background in mathematics. You should review some of the principles of algebra including logarithms and solving quadratic equations
Know the periodic table well
We have previously discussed the periodic table as one of the basic pillars of chemistry; you should know and understand the most famous elements of it and know its different divisions (metals, ellipses, semiconductors, inert elements, radioactive elements, etc.)
Focus on the basics well
First, start with the following topics (measurement methods, chemical methods, chemical symbols and their implications, and atomic structure). Many students often find it difficult to understand chemistry because they do not understand basic principles well! Which prevents the depth of this specialization.
Depends on visual means
There are many programs and applications that allow you to simulate many laboratory experiments that you may not be able to do on your own; there are also applications that enable you to study compounds and molecules in a 3D image such as Chem Draw. I also advise you to watch any videos or educational documents in this specialty and do not rely on books and references only!
You have had difficulty understanding some of the chemical topics Please tell us through comments
