You are watching: Why do elements in the same family share properties
The slrfc.orgical habits of atoms is managed by their electron configuration. Since the family members of aspects were organized by their slrfc.orgical habits, it is predictable that the individual members of each slrfc.orgical family will have equivalent electron configurations.
Families of the Periodic Table
Remember that Mendeleev arranged the routine table so that aspects via the a lot of comparable properties were placed in the same team. A group is a vertical column of the routine table. All of the 1A elements have one valence electron. This is what causes these facets to react in the exact same means as the other members of the family. The facets in 1A are all incredibly reactive and also form compounds in the very same ratios via similar properties via various other aspects. Because of their similarities in their slrfc.orgical properties, Mendeleev put these elements right into the exact same team. Group 1A is likewise well-known as the alkali metals. Although most steels tfinish to be exceptionally difficult, these metals are actually soft and deserve to be conveniently reduced.
Group 2A is likewise referred to as the alkaline earth metals. Once again, bereason of their similarities in electron configurations, these elements have actually similar properties to each other. The same pattern is true of other teams on the regular table. Remember, Mendeleev arranged the table so that aspects via the a lot of similar properties were in the same group on the regular table.
It is necessary to recognize a couple of various other vital groups on the periodic table by their group name. Group 7A (or 17) facets are additionally called halogens. This group includes extremely reactive nonmetal facets.
The noble gases are in group 8A. These elements additionally have comparable properties to each other, the most significant home being that they are very unreactive, seldom forming compounds. We will certainly learn the factor for this later, when we talk about just how compounds develop. The facets in this group are likewise gases at room temperature.
If you can locate an aspect on the Periodic Table, you deserve to use the element"s place to figure out the energy level of the element"s valence electrons. A period is a horizontal row of facets on the regular table. For instance, the elements sodium ((ceNa)) and magnesium ((ceMg)) are both in duration 3. The facets astatine ((ceAt)) and radon ((ceRn)) are both in period 6.
