Using English to Classify The Composition of Matter in Chemistry


CLASSIFICATION OF MATTER

A.    Atom
Atom is the smallest unit of matter consisting of a core, which contains protons (+ charge) and neutrons (neutral), and skin that contain negatively charged electron is. Some say that the atom is a constituent element of the particle.
B.     Element
Element is a group of atoms have the same number of protons in its nucleus. This number is known as the atomic number of the element. The element is defined as a single substance that can not be divided again into smaller parts.
C.     Molecule
The molecule is a combination of atoms, can be two or more. This means that when it comes to the molecule that is conceivable combination of atoms. The molecule is the smallest particle of an element / compound.
D.    Ion
Ions are electrically charged atoms, ions  electrically charged ions are called, and negative charged ions called anions. Cation and anion can be a single ion is composed of one type of atom or can also be polyatomic ions containing two or more different atoms.
E.     Compound
The compound is a single substance that consists of several elements intertwined. The compound formed from at least 2 different elements. Though formed from different elements, but still called the compound a single substance, because the properties of the elements that shape can not be found in the compound.
Differences compounds and molecules are any compounds are molecules per molecule, but not necessarily the compound. The compound is a combination of at least 2 different atoms, molecules and combinations of at least 2 atoms can be the same or different.
   
F.      Mixture
The mixture is a substance composed of several types of substances and other non-permanent arrangement of elements and compounds. The mixture is a material consisting of two or a single substance. The material that we encounter everyday almost everything mix.
The mixture can be divided into three types, namely:
1. The mixture was homogeneous = Solution
2. Mix Heterogeneous = suspension, and
3. Mix the situation between suspensions and solutions = Colloidal
The solution is a mixture of two or more substances consisting of solute and solvent. Condensation particle size is very small, less than 1 nm, so it can not be seen by using a microscope ultra though. and indistinguishable between solute and solvent medium. Substances in the solution can not be separated by filtration.The suspension is a mixture of coarse and heterogeneous. The particle size of the suspension of more than 100 nm.Colloid is a mixture consisting of dispersed particles and dispersing particles. Colloidal particle size lies between 1 nm - 100 nm. Or in other words the situation colloidal particle size between suspensions and solutions.

  1. Hiiii Desi, I'm Novi, Want to ask you, What is the difference between Solution, suspension, and Colloidal? Please, give me a examples

    1. Hi Novi, Thanks for question. The solution is a mixture of two or more substances which consist of solute and solvent. The particle size of the solution is very small, less than 1 nm, so it can not be seen using an ultrasound microscope. And can not be distinguished between the solute and the solvent medium. The substances in the solution can not be separated by filtration. An example of a sugar solution, we can not tell which sugar is water in a sugar solution. Some examples of solution are salt solution, acid-base solution and others. While Suspension is a rough and heterogeneous mixture. The particle size of the suspension is more than 100 nm. An example of a suspension is a mixture of flour in water, does it still look flour? The answer is Yes, still. This mixture initially looked like a cloudy solution, but gradually separated due to the influence of gravity (undergoing precipitation). Suspension can be separated by filtering. Examples of other suspensions include lime with water, soil with water, ice cendol, mixture of sandstone with sand and others. And Colloid is a mixture composed of dispersed particles and dispersing particles. The size of the colloidal particles lies between 1 nm - 100 nm. Or in other words the size of colloidal particles is the state between suspension and solution. Examples of colloids are milk, coconut milk, soap water, and paints. Colloids appear cloudy but stable (not separating / settling). The material in the colloidal mixture can not be separated by conventional filtration, but by using an ultra filter.

    1. Thanks to Intan have asked, the example of the atom is like sodium (Na), while the example of that element is a collection of sodium (Na), the example of a molecule is H2O, whereas the example of the compound is a collection of molecules H2O, and the example of the ion is H+.

  3. Why the elements that lie on the same perode have differences?

    1. Hi Atma,Thanks your question, actually each element is different but for easy to learn made equation between element dabel table periodic

    1. Hai Indri, thanks your question. Atoms are the smallest part of an element that still has the same properties as that element. The atom consists of; Proton (positively charged), Electron (negatively charged) Neutron (not charged / neutral). The ion is an atom or a set of electrically charged atoms. Positively charged ions are called cations while negatively charged ions are called Anions. Ions consist of one atom called Single Ion whereas an ion consisting of two or more atoms is called Ion Poliatom.

  5. In the mixture there are dissolved and solvent, how to distinguish solvent and dissolve in mixture?

    1. How to distinguish solvent and solute that is the amount of solvent more than the solute, and the solvent looks solute not solute.

      Hapus
