Basic Materials particles

Can be:
1) Atom
 Atom is the smallest particle of an element that still has elements of nature that
 Atom elements are given a badge with the symbol of the element
 Example: Na, Mg, Ba, Ca, Fe

2) molecule
 molecule is neutral particles that consist of 2 or more atoms, the atom and the atom is a kind of different.
 molecule that consists of a kind of atom molecule called Element
 molecule that consists of atom-atom molecule called a different compound
 Example: H2O, CO2; H2SO4

3) Ion
 Ion is the atom or group of atoms that had electricity
 Ion who had called Kation positive, while the negative ion which had called anion
 Ion consists of 1 atom called Ion Single (monoatom), while the ion consists of 2 or more atoms called Ion Poliatom
 Examples:
Single Kation: Na +, K +
Kation Poliatom: NH4 +, H3O +
Single anion: Cl-, S2 -
Anion Poliatom: NO3-,-OH


Element particles (atom can form, can be a molecule)
a. In general, every element, including metal particles have a form of Atom
b. Only a few non-metallic elements that form partikelnya molecules (eg hydrogen H2; fosforus P4; sulfur S8)
c. Molecules that consist of 2 atom molecule called Diatomik (eg, molecular hydrogen, nitrogen)
d. Molecule that consists of more than 2 atom molecule called Poliatomik (eg molecular fosforus, sulfur)

Compound particles (can be a molecule, can form ion)
o Can a molecule (called a molecular compound) or Ion (compound called Ion)
o compound of metal ion including the compound, while the compound of the non-metallic elements including molecular compound.
Example molecular compound: water (H2O); compound ion: Calcium carbonic (CaCO3)
