Give the name and location of details groups ~ above the routine table, consisting of alkali metals, alkaline earth metals, noble gases, halogens, and shift metals. Describe the relationship in between the benidormclubdeportivo.orgical behavior of family members in the routine table and also their electron configurations. Identify facets that will have the most similar properties come a offered element.

You are watching: What do all elements in a group have in common


The benidormclubdeportivo.orgical behavior of atoms is controlled by your electron configuration. Because the family members of elements were arranged by your benidormclubdeportivo.orgical behavior, that is predictable that the individual members of every benidormclubdeportivo.orgical family members will have similar electron configurations.


Families the the routine Table

Remember that Mendeleev i ordered it the regular table for this reason that facets with the most comparable properties were placed in the exact same group. A group is a vertical pillar of the routine table. Every one of the 1A aspects have one valence electron. This is what reasons these aspects to reaction in the same methods as the various other members the the family. The aspects in 1A room all an extremely reactive and form compounds in the same ratios with similar properties with various other elements. Due to the fact that of your similarities in their benidormclubdeportivo.orgical properties, Mendeleev put these aspects into the very same group. Group 1A is additionally known together the alkali metals. Although most steels tend to be an extremely hard, these steels are in reality soft and also can be easily cut.

Group 2A is additionally called the alkaline earth metals. As soon as again, due to the fact that of their similarities in electron configurations, these aspects have similar properties to each other. The same pattern is true of other groups on the periodic table. Remember, Mendeleev i ordered it the table so that aspects with the most comparable properties to be in the same team on the regular table.

It is necessary to identify a pair of other necessary groups ~ above the routine table by their group name. Group 7A (or 17) facets are likewise called halogens. This group contains really reactive nonmetal elements.

The noble gases room in group 8A. These elements likewise have similar properties to every other, the most far-reaching property being that they are incredibly unreactive, rarely creating compounds. Us will discover the reason for this later, when we talk about how compound form. The aspects in this team are also gases in ~ room temperature.

If you can locate an aspect on the routine Table, you can use the element"s place to number out the power level of the element"s valence electrons. A period is a horizontal row of facets on the routine table. Because that example, the facets sodium (\(\ceNa\)) and magnesium (\(\ceMg\)) space both in duration 3. The aspects astatine (\(\ceAt\)) and radon (\(\ceRn\)) space both in period 6.

Summary

The upright columns top top the regular table are referred to as groups or families because of their similar benidormclubdeportivo.orgical behavior. All the members of a family members of elements have the same number of valence electrons and comparable benidormclubdeportivo.orgical properties. The horizontal rows on the regular table are dubbed periods.
