Elements, Compounds and mixtures :
Nomenclature of Compounds Erika G., Juanita A. : :
-
The combining of elements exchange their valences. In the first, iron uses valence 3 and oxygen uses valence 2.
- Non Metal Oxides: CO2, CO, Non metal oxides are the covalent oxides of non metals with oxygen that react with water to produce acids or with bases to produce salt
- Salts: NaCl, Lif, BeBr2, In chemistry a salt compound is a chemical compound consisting of an ionic assembly
-
-
- Acid: HF, HCI, HBR, A substance with particular properties, the acid disolve some metals
- Oxo Acid: H3PO4, H2SO4, HNO3, An oxo acids is an acid that contains oxygen, specifically its a compound that contain hydrogen, oxygen and at least one other element
- Metal Oxides: FEO, CAO, MGO, The sufer of the metal oxides is a key factor for effective interaction with target molecules
- Peroxides: H2O2, A compound containing two oxygens atoms bonded together in its molecule

Atomic structure is made from a atom that have positive charged. Rutherford ,Francis rick and James waston they discover the atomic structure.rutheford he born in 30 august of 1871 in New Zealand and die in October of 1937.atomic models:
Democrotic:it says that the democratic says that atoms are homogenius,eterns , they can't divide and are invisible
-
dalton:Dalton proposed that each of the atoms of an element, such as gold, is identical to every other atom of that element. He also observed that the atoms of one element differ from the atoms of other elements.
Sommerfeld's atomic model consists of the explanation of the behavior of electrons, stating that within the same energy level different energy sublevels could exist, which caused different energy variations to occur in the same level.
-
-
Rutherford's Model established: The atom has a central nucleus in which the positive charge and practically all the mass are concentrated. The positive charge of the protons is balanced by the negative charge of the electrons, which are outside the nucleus.
Bohr described the fundamental hydrogen atom as an electron moving in circular orbits around a proton, the latter representing the nucleus of the atom, which Bohr located in its central part and giving a robust explanation regarding the stability of the electron's orbit and of the atom as a whole
The atom is made up of a sphere of matter with a positive charge, in which electrons are embedded in sufficient numbers to neutralize its charge.
-
Lewis formula is a graphic representation that shows the bonding electron pairs between the atoms of a molecule and the lone pairs of electrons that may exist.

Perodic Table
Groups of elements
Your table presents an organization into rows (periods) and columns (groups) with similar chemical properties.
History:
-
Mendeleyev orders the elements known for their atomic mass and valence, creating the first version of the periodic table.
-
-
By:Noa Valarezo Cabrera, Nicolas Catolico Diaz.
Groups definition:
Metals
Alkai metals:They are soft, shiny metals with low melting points. Alkali metals react readily with air and moisture. Due to their reactivity, special precautions must be taken when using and storing these metals.
-
Alkaline Earth Metals : They are called "alkaline" earth metals because they form "alkaline" solutions, hydroxides, when they react with water .
-
-
-
Transition Metals:A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals.
Post transition Metals:The chemistry of the post-transition metals is largely that of ionic compounds greatly affected by tendencies to directional/covalent bonding and polarising effects.
-
Metaloids: They have a metallic luster, and generally look like metals. They are brittle, and easily shattered. Metalloids can conduct electricity, but not as well as metals.
-
Nonmetals:
Noble Gases:A gaseous chemical element that does not readily enter into chemical combination with other elements
-
Other nonmetals:poor conductors of heat and electricity, and are not malleable or ductile
Nomenclature is the process of naming chemical compounds with different names so that they can be easily identified as separate chemicals

An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen ion, H+),The first category of acids are the proton donorsacids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word acid is derived from the Latin acidus, meaning 'sour'.
