The elements of the Universe Compounds and elements
Pure substances: Have specific properties that identify them. Can be of two types: •
Compounds: If can be decomposed into simpler substances by chemical methods. (Water, H20). Simple substances or elements: Can not be decomposed into simpler substances. (Oxygen, 02). Internenes

The elements of the Universe Matter is composed atoms.
Atoms are the smallest particles of a chemical element. Are composed of protons and neutrons in the core, and the electrons in the crust.
Internenes
PiensoyJuego
The elements of the Universe Composite substances are formed by the ing of two or more different atoms, and its constant proportion in each molecule. For example. Water (H2O) The chemical elements are made up of equal atoms, but different from those of other elements. Internenes
PiensoyJuego
The elements of the Universe The atomic number is the difference between an atom of another, therefore the number of protons. Are ordered increasingly forming the periodic table of elements.
Each element has a name and is represented by a symbol composed of one or two letters. The first is capitalized and the second is always lowercase. Internenes

PiensoyJuego
The elements of the Universe The atoms are arraged in substances of different types:
Isolated atoms: inert gases (not react). Molecules: binding of two or more atoms. Simple substances: molecules of identical atoms. Complex substances: molecules of different atoms. Crystals: union of many atoms, forming strong associations of both simple substances (carbon, gold) and compound (salt).
Internenes
PiensoyJuego
The elements of the Universe Substances and formulas Formula: A chemical formula is a way to represent the substance. They write the symbols of all elements with subscripts indicating the number of atoms of each class. Molecules:
Simple substances: O2 Complex substances: H20.
Crystals:
Elements: C Crystal compounds: FeS2 Internenes
