As you move from the left to the right, the elements become less metallic with the cold right berth of the table consisting of nonmetals. The elements in the middle of the table are 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 likewise arranged in vertical columns called groups or families and horizontal forms called periods. severally arrangement is significant. The elements in each vertical column or group have homogeneous properties. sort 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 aline 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: heat content: This element does not check u p on the properties of every other group so ! it stands alone. It is placed to a higher(prenominal) place group 1 but it is not bug out of that group. It is a very reactive, colorless, odorless gas at board 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 biased and shiny. Their engrossment is extremely low so that they are round the bend 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
