What is Molecule?

Molecule is a bound knowledge with atom. Relationship between molecule and atom very tight. Even every molecule must have an atom. Why it can be like that? So, atoms are very rare found alone, because generally atoms adhere or mutually bind each other. The  signification from molecule is a group of atom which bind each other and forming a small part from a substance or compound usually alone. Like an atom, molecule still very small to be seen with natural eyes. In this post I will talked about molecule bro, I will discuss is about leather and bind, water molecule, chemical formula and molecule models. So let’s read about this topic.

A. Leather and Bind

Atom has leather that fill with electrons. The first leather can be filled with 2 electrons, the second leather and the third leather can be filled with eight electrons, eventough some electrons has until 18 electrons in the third leather. When a leather is full, electrons will start a new leather, an atom called stable if the last leather is full.

Atom bind each other become stable, the atom do that stuff with sharing the electrons or it can be called give or take electrons from the other, untill the capacity of electrons in the last leather can be full, and reqruit the stable condition. For the example two hydrogen atoms that bind will make electrons in the last leather full, that is every first leather has 2 electrons. See the following picture:

The other example is water molecule, consist of two different atoms, such as hydrogen and oxygen. Two hydrogen atoms share electron with oxygen atom, so every leather have a complete electrons. Oxygen atom use two electrons (one of every hydrogen atom) to complete the outer leather. So all atoms is stable. If you still don’t understand, I will try to explain more detail.

Oxygen atom has 6 electrons in the outer leather. So the oxygen atom need two more electrons to complete the outer leather and become stable. Whereas  every hydrogen atoms has one eletron in the outer leather so it need one more to became stable. When they bind, hydrogen and oxygen atoms mutually give and take, so it became stable and the outer leather has a complete electron.

B. Chemical Formula

A symbol can represent a name from atom, this symbol called chemical symbol. Generally the first and the second letter from the name in English, Latin or arabic. For example:

O         is a symbol for oxygen

Au       is a symbol for gold from latin word Aurum

Fe        is a symbol for iron from latin word ferrum

K          is the symbol for potassium from arabis word

A chemical formula show everything which arrange a substance and its proportion. For example every carbondioxide molecule consist of one carbon atom and two atoms oxygen, so the formula for carbondioxide is CO₂. The rate 2 shows how many oxygen atom in that molecule.

C. Molecule Models

When we learn about molecule, the scientist use a model to offer. There are two main types such as ball type and bar type also filling space model.

Whereas in filling space models, atoms are showed mutually adhere.

The both models don’t seem like a real molecule, but it is the simple way to describe atoms that arrange molecule.

That’s all my post about molecule, with my limited knowledge I try to sharing with you all. Eventough there are many lack, I’m sure you get advantages that add your knowledge more. If you have any comment for my blog. Write it in the comment Box.
