GROUPS OR FAMILIES: They are vertical jamie oliver tableware groupings that indicate they have similar chemical properties because they have the same valence electrons. In the periodic table are ordered in groups A and B. a) GROUP A: They are located at the ends of the periodic table. We denote the number of electrons in the last layer and are represented in Roman numerals. They end up in the sublevel "s" and "p" a) GROUP B: They are located in the central area of the periodic table. The number of electrons in the last layer, the group does not tell us, because the valence is variable. The electron configuration ends in the sublevel "d". The inner transition elements called rare earth: its electron configuration ends in "f". Have eight subgroups. The group VIII B has 3 lockers. Classification of chemical elements jamie oliver tableware chemical elements can be classified into: Metals, nonmetals, metalloids (amphoteric) and noble gases. Metals jamie oliver tableware are good conductors of heat and electricity. Are oxidized (lose electrons). Are also called reducers. They are electropositive. Are solid, except for mercury (liquid at room temperature). No metals are poor conductors of heat and electricity. Are reduced (gain electrons). Are also called oxidants. They are electronegative. At room temperature the majority are in the solid state. As gases are N, O, F, Cl, H and in the liquid state or amphoteric Metalloids Br: These elements are metallic and nonmetallic jamie oliver tableware properties. Occupy a diagonal region is observed in the periodic table (transition between metal and nonmetal), among them we can find the B, Si, Ge, As, Sb, Te, Po. Noble gases are chemically stable elements by having jamie oliver tableware your last layer 8 and, with the exception of He which has 2 and plotted. n s2 p6 not combine with any other element. Temperatures only demanding the Xe can react. Its molecules are monatomic. According to its electron configuration, chemical elements are classified as noble gases, representative elements and transition elements. jamie oliver tableware 1. Noble gases are those located at the far right of the periodic table in group 0, or VIII A (also 18). Atoms of these gases, with the exception of helium have 8 valence electrons. This means that the last energy jamie oliver tableware level has its full orbital (8 e-) distributed jamie oliver tableware according to the configuration n s2 p6. Where "n" represents the outermost energy level. Two. Representative elements: are located in groups A of the periodic table. These elements have their valence electrons in orbitals "s" or "p" and external configurations ranging from n to n s1 s2 p5, excluding the 1s2 (corresponding to helium a noble gas). Three. Transition elements: They are in the B groups of the periodic table. Their atoms exhibit more complex configurations, the valence electrons are in orbitals "d" or "f".
