    The periodic table is composed of eighteen columns and seven horizontal rows, with two additional rows underneath. There is grand total of 112 elements in the periodic table, each of which is placed in a designated spot on the table and cannot be moved. Different areas on the table have elements that are made of different components. Elements that are in the same column are more similar than elements in the same horizontal row. Seventy five percent of the table is made up of metals, and a couple of the columns on the right of the table have gases. There are only two elements that are liquids- mercury and bromine. Column 1 contains the alkali metals, which suddenly combust when exposed to air or water. Columns 3-12 are the transition metals, which contain heavier atoms, which are more flexible in how they organize their electrons. Column 17 is made up of the more reactive gases- the halogens. The noble gases are in column 18. The electrons are the most significant part of an atom. When atoms don’t have the sufficient number of electrons they need in their outer level, they will do whatever they can to get the number they need. The number of protons an atom has is its atomic number. The atomic number plus the number of neutrons the atom has is the atom’s atomic weight.…

    3. Alkali metals (group 1) have 1 electron in their outermost energy level, the s sublevel, and they want to lose that electron, that is why alkali metals react vigorously with nonmetals, especially halogens, because halogens need 1 electron to be stable. All alkali metals react with water to produce hydrogen gas and substances called alkalis. Alkaline earth metals (group 2) are less reactive than alkali metals because alkaline earth metals have 2 electrons in the s sublevel. Because the main energy level is filled, they are less likely to lose or gain an electron.…

    This experiment tested the theory that the elements in the periodic table are arranged in a manner in which the elements of a group share similar chemical properties. The elements we used were the ones from the alkaline earth metal group. These elements tend to form 2+ cations and are very reactive. We also compared these elements to that of lead because lead also forms a 2+ cation. We used the chemical property of solubility to observe the periodic trends of the alkaline earth metals. As a general rule, reactivity increases as you move down a group in the periodic table. This means in regards to solubility that the more you farther you move down the group the more insoluble the element is when combined with hydroxides, chlorides, bromides, iodides, sulfates, carbonates, and oxalates. My results were consistent with this theory in that the mixtures went from no reaction to forming a precipitate or from forming a light precipitate to a heavy one as the elements moved down the periodic…
