The Periodic Table of Elements
The periodic table is a table of the chemical elements, which are arranged by order of atomic number, and by the properties. It contains periods (horizontal lines) and groups (vertical lines).The elements in groups have some similar properties with each other. The periodic table is a masterpiece with chemical information. The periodic table is divided in ten categories, group 1 (except hydrogen) are alkali metals. Group 2 are alkali earth metals. Group 3 to group 12 are transition metals, and finally we have the rest of the metals: basic metals, semi metals, non metals, halogens, lanthanides, noble gases and actinides. The elements and compounds have been helping people to learn about their physical and chemical …show more content…
There’s two types of chemical reactions: Synthesis, Decomposition, Single Replacement, Double Replacement and Combustion. In a chemical reaction there’s two sides: Reactants and Products sides; the reactants side is the one to the left which are the elements or compounds that you’re starting with and the products is the result you get at the end of all the reaction. Synthesis means to combine, for example you have to elements in the reactants side like Hydrogen (H) and Oxygen (O), and they will become H2O because we can’t forget to balance them with their type of charge. Decomposition is when you have in the right side a compound like H2O and you’re going to separate them into H2 and O. Single replacement is when in the reactants side you have a compound plus an element by itself and in the products side you are going to have the same but one element from the compound will combine with the element that was it by itself; for example A+BC →AC+B. Double Replacement is similar to the last one only that in both sides you have compounds so now this time will be like this AB+CD→AD+BC. The last one will be Combustion where in this one all you need to know is that in the reactant side you need to have O2 and in the products side you need to have CO2 and H2O; for example:
