Color Coding the hourly Table Student training Sheet The Periodic Table is a list of wholly the known elements. It is organize by increasing atomic number. at that place atomic number 18 two main radicals on the periodic evade: metals and nonmetals. The remaining align of the slacken contains elements with the greatest met altogetheric properties. As you move from the left to the right, the elements become less metallic with the far-off right berth of the table consisting of nonmetals. The elements in the middle of the table ar called modulation elements because they are changed from metallic properties to nonmetallic properties. A small group whose members touch the zigzag line are called metalloids because they adopt both metallic and nonmetallic properties. The table is alike arranged in vertical columns called groups or families and horizontal trends called periods. separately arrangement is significant. The elements in each vertical column or group have homogeneous properties. throng 1 elements all have the electron in their satellite shells. This gives them analogous properties. Group 2 elements all have 2 electrons in their out shells. This also gives them similar properties. Not all of the groups, however, hold accepted for this pattern. The elements in the commencement exercise period or row all have nonpareil shell. The elements in period 2 all have 2 shells. The elements in period 3 have 3 shells and so on.

There are a number of major groups with similar properties. They are as follows: hydrogen: This element does not che ck up on the properties of whatsoever other! group so it stands alone. It is placed to a high place group 1 but it is not plowshare of that group. It is a very reactive, colorless, odorless gas at path temperature. (1 outer aim electron) Group 1: Alkali Metals These metals are super reactive and are never found in personality in their pure form. They are silver saturnine and shiny. Their engrossment is extremely low so that they are haywire adequate to be cut with a knife. (1 outer level electron) Group...If you loss to get a full essay, order it on our website: BestEssayCheap.com
