As an introduction to chemistry, it is the branch of science that studies matter and change. First, chemistry deals with the study of the composition and the properties of matter (which is basically any macroscopic substance that we can observe). Then, chemistry deals with change, or how these substances evolve when submitted to certain conditions,...
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 t...
Everythingis chemistry. Everything that you can observe macroscopically is made ofchemicals. You are made of chemicals, your food is chemicals, you breathechemicals, we live out of and thanks to chemicals, everything you see under thesun is a mixture of chemicals. Everything you see or do is based on chemical concepts and processes. Fireworks going...
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 ...
Chemistryis the science that studies and manipulates matter. We human beings are gettingpretty good at it, (although it is not easy to beatNature), but we arefar from an ideal position in which we can easily make any molecule or compoundat will in a matter of minutes. That isprobably the future of chemical synthesis, being able to shape any compoun...
An atomis defined as the basic unit of a chemical element. A fundamental piece of matter. Plain simple and basic chemistry concept. Obviouslywe now know that atoms are made of smaller particles, called subatomicparticles: protons (positively charged by convention), electrons (negativelycharged by convention) and neutrons (neutral particles). In sim...
A moleculeis a group of atoms bound together. It’s the next level of chemical complexity. Molecules represent the basic unit of a chemical compound, and this another of those essential basic chemistry concepts. That’sbasically it. An example is a water molecule, which is made from two atoms ofhydrogen (H) and one atom of oxygen (O), held together v...
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. 1. In molecules (such as water, or H2O, see above), which are neutral compounds of “indiv...
The periodic table is a list or arrangement of all known chemical elements. These are organized in a way that it allows grouping elements with similar atomic structure, and therefore, similar properties. The main criteria for this order is the arrangement by increasing atomic number, which is the number of particles of that element’s nucleus (proto...
Chemistrystudies changes in matter. A chemicalreactionis a process in which one set of chemical compounds aretransformed into another. Reaction occur when there is an interaction betweenthe compounds in which some initial bonds are broken and some new bonds areformed. Why does this happen? In simple terms, because the energy holding the new bonds t...
Jun 23, 2022 · The definition of chemistry—the study of the interactions of matter with other matter and with energy—uses some terms that should also be defined. We start the study of chemistry by defining basic terms.
Jan 23, 2021 · What is chemistry? Simply put, chemistry is the study of the interactions of matter with other matter and with energy. This seems straightforward enough. However, the definition of chemistry includes …
