Different Topics In Chemistry 101


In school, many students doesn't like the subject of chemistry. Our day to day living is affected by chemistry. In this article, we will discuss the basic topics in chemistry 101.


The study of matter is one of the basic topics of chemistry 101. It is the atom and molecules that basically makes up matter. An atom is the one that is only composed of a single element, like gold, silver, and potassium. Water and carbon dioxide is made up of two or more atoms and are called molecules. A two different substance can also be called a matter.


It is the atoms that make up any matter. But atoms are not the smallest units of matter. The most basic component of atoms are proton and neutrons. The negatively charged particles are electrons while the positively charge are the protons and the neutrons don't have any charged. The number of protons present o each atom differentiates the from one another. A hydrogen atom has only one proton while a carbon atom has 12. Neutral particles do not have any charge, and that's basically what an atom is. The number of protons and neutrons in an atom is equal. If the atom has more electrons, then it will have more reaction. Only a single type of atom composes one element. Continue reading below or visit https://en.wikipedia.org/wiki/Chemistry.


Molecules is defined as the combination of one or more atom that is chemical bond together. Depending on the chemical properties, the type of bonds in a molecule is defined. He outermost energy level of a molecule is based on its electrons. The outermost energy level of molecules is full. Helium and neon gasses which are also known as noble gasses have no molecules because of the full outermost energy it has. Solid, gas and liquid are the physical properties of an atom and is determined by how strong their bonds are with each other.


The existence of molecules and atoms can be seen in the three states of matter and that is solid, liquid, and gas which is also discussed in flow chemistry 101 It is solid that has the higher molecular structure followed by liquid which is also followed by gas. Due to their far molecular structure, gas molecules seldom interacts with each other.


When a homogenous mixture of two or more substances is mixed in a single phase like a liquid, this is known as a solution and this is also discussed in chemistry 101. The one that has a lesser amount is known s the solute, and the one which has more is the solvent. One example is sea water, the solute is salt while the water is the solution. In order for solutes and solvents to dissolve each other they should have the same polarity if they do not have, then nothing will be dissolved. One solution that doesn't dissolve each other is oil and water. You may as well read about continuous stirred tank reactor
