For that reason, I decided to go ahead and explain here 15 important basic chemistry concepts, which hopefully will get you in a better shape for learning chemistry. These are clearly explained in most of the chemistry textbooks in our review.

We will start off with an introduction to basic chemistry: background on the most basic definitions of chemistry, a bit of history, and highlighting why and how chemistry is important. The basic units in chemistry will be defined: atoms, molecules, subatomic particles. Then, we will discuss them from a beginner point of view, and formulate them in the format of questions.

Very simple chemical processes were performed even during ancient history, at 1000 BC, much before any basic chemistry concepts or laws were actually established. Extraction of metals from ore or getting compounds out of natural sources such as plants, are examples of chemistry that was first performed thousands of years ago and are still a thing today.

A all sciences are glued together by basic chemistry concepts, thats why it is called the central science. Without chemistry, physical sciences (which include chemistry itself), would find a gap and not be bound to life sciences (such as biology) and applied sciences (such as engineering). This is important to note in any introduction to chemistry text.

There are three basic types of chemical compounds, and should be briefly introduced in this post about basic chemistry concepts. All of them are the result of bonding atoms together. The difference is in the nature of the forces that hold together those atoms.

Chirality is a geometric property of certain molecules. A molecule is said to be chiral when its mirror image is not superimposable to the molecule itself. The classical source of chirality in a (organic) compound is the presence of a carbon atom with four different substituents. The concept is far better explained by this basic chemistry youtube video:

The origin of chirality, together with the origin of life is one of the most relevant questions in, not only chemistry, but science in general, so it is not possible to answer in a straightforward manner. The main theory backing it up is based on homochirality, which could have emerged over three steps: mirror-symmetry breaking, chiral amplification and chiral transmission. This is far beyond basic chemistry concepts, but you can further read about it here.

Finally, I want to make an update with a 16th concept! This deserved a separate post, and here it is: A tutorial review on why chemicals react! If you are serious about learning chemistry, you need to master the basics behind the concepts of thermodynamics and kinetics.

To wrap up, I hope you all (or your students, or children) got something out of this. As I mentioned above, this is just a simple introduction to many basic chemistry concepts. If something is not clear enough, or want me to further develop or update any particular point, please, make sure to let me know.

In the scope of its subject, chemistry occupies an intermediate position between physics and biology.[6] It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.[7] For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence at a crime scene (forensics).

Energy and entropy considerations are invariably important in almost all chemical studies. Chemical substances are classified in terms of their structure, phase, as well as their chemical compositions. They can be analyzed using the tools of chemical analysis, e.g. spectroscopy and chromatography. Scientists engaged in chemical research are known as chemists.[15] Most chemists specialize in one or more sub-disciplines. Several concepts are essential for the study of chemistry; some of them are:[16]

The chapter is one of the most fundamental and important chapter in whole of Chemistry. There are some 2-4 basic questions that comes in NEET from this chapter on important topics like mole concept, limiting reagent, others like molarity, molality etc.

Some basic concepts of chemistry are the most basic chapter of chemistry. It has various important concepts that you need to have greater insights for a better understanding of the whole of the chemistry. This article will help you to give important insights into this chapter and will also guide you in some important tips and guidelines.

The aim of this post is to reach a consensus on what we should do with basic or Googleable questions. Please provide your insights in comments or answers.If you're going to post an answer, please specify exactly what needs be done about a "basic" question. If convenient, draw a distinction between "Googleable" questions, easy questions, and possibly "Googleable questions that need some search-master voodoo".

Or, not? Are we only interested, say, in questions clearly asked from some base of accurate chemical understanding, the answers to which require knowledge beyond what one would acquire in, e.g., the first year of a "typical secondary-school education"?

Questions for which a quick search turns up the desired answer, but where it takes someone sufficiently knowledgeable in chemistry to be confident that it is the answer, should be left open. These seem like great questions & answers to have on the site, because they provide a helpful clarification of information available elsewhere. Each such question does represent a judgment call by the community, though, because the evaluation of it takes someone sufficiently knowledgeable is not an objective thing.

Questions of type (1) almost always fall under homework, and I think our current policy of aggressive closure is appropriate. I have to imagine almost everyone asking these types of questions has access to an educational/academic context in which they could ask them (teacher after school, office hours, classmates, etc.), and they will be much better helped by talking to someone who can sit down with them and work with them point-by-point. There may be some small number of self-learners asking these sorts of questions as they're just starting out, and it would be nice to be able to be a resource for them, but a Chem.SE Q&A is a terrible format for such help.

Students will record their observations and answer questions about the activity on the activity sheet. The Explain It with Atoms and Molecules and Take It Further sections of the activity sheet will either be completed as a class, in groups, or individually depending on your instructions. Look at the teacher version of the activity sheet to find the questions and answers.

The students of the science stream must be aware that chemistry is a branch of science that deals with the composition, structure, properties, and characters of different matter. Chemistry is also known as the science of atoms and molecules. While knowing your class 11 chemistry syllabus is important is also essential to be through with the course. This blog will cover some vital and important study notes related to chapter 1 of some basic concepts of Chemistry class 11.

Chapter 1 of some basic concepts of Chemistry Class 11 also discusses the properties of different substances and their unique characteristics and properties. Having said that, the properties can be divided into two types:

The concept of significant figures in chapter 1 of some basic chemistry class 11 explains that the reliability of a measure is given by the number of digits used to represent it. To put it more precisely, we use figures which are known with certainty. These numbers are known as significant figures. They contain all specific figures plus a questionable figure in a number. 2351a5e196
