give the name and also location of particular groups ~ above the routine table, consisting of alkali metals, alkaline planet metals, noble gases, halogens, and transition metals. Explain the relationship between the ptcouncil.netical behavior of family members in the periodic table and also their electron configurations. Identify facets that will have actually the most comparable properties come a given element.

You are watching: All the elements in the same group have the same


The ptcouncil.netical actions of atom is regulated by your electron configuration. Due to the fact that the families of elements were arranged by their ptcouncil.netical behavior, the is predictable that the individual members of each ptcouncil.netical household will have comparable electron configurations.


Families of the periodic Table

Remember the Mendeleev arranged the periodic table therefore that elements with the most similar properties were placed in the same group. A group is a vertical column of the periodic table. Every one of the 1A facets have one valence electron. This is what reasons these elements to reaction in the same ways as the various other members of the family. The facets in 1A room all very reactive and kind compounds in the exact same ratios with similar properties with various other elements. Due to the fact that of your similarities in your ptcouncil.netical properties, Mendeleev put these aspects into the exact same group. Team 1A is additionally known as the alkali metals. Although most steels tend to be really hard, these metals are in reality soft and also can be conveniently cut.

Group 2A is additionally called the alkaline planet metals. As soon as again, since of your similarities in electron configurations, these facets have comparable properties to each other. The very same pattern is true that other teams on the routine table. Remember, Mendeleev arranged the table therefore that aspects with the most comparable properties to be in the same team on the periodic table.

It is vital to identify a pair of other vital groups top top the routine table through their group name. Team 7A (or 17) aspects are additionally called halogens. This team contains an extremely reactive nonmetal elements.

The noble gases room in group 8A. These elements also have comparable properties to each other, the most far-reaching property being that they are very unreactive, rarely developing compounds. We will discover the factor for this later, as soon as we comment on how link form. The facets in this team are also gases in ~ room temperature.

If you can locate an element on the regular Table, you have the right to use the element"s position to number out the energy level that the element"s valence electrons. A period is a horizontal row of aspects on the periodic table. Because that example, the elements sodium ((ceNa)) and magnesium ((ceMg)) are both in period 3. The aspects astatine ((ceAt)) and radon ((ceRn)) room both in period 6.

Summary

The vertical columns on the routine table are called groups or families due to the fact that of their comparable ptcouncil.netical behavior. Every the members that a family of facets have the same number of valence electron and comparable ptcouncil.netical properties. The horizontal rows ~ above the regular table are dubbed periods.
