provide the name and location of details groups top top the regular table, including alkali metals, alkaline earth metals, noble gases, halogens, and shift metals. Explain the relationship between the stclairdrake.netical behavior of households in the periodic table and also their electron configurations. Identify aspects that will have actually the most similar properties come a provided element.

You are watching: Vertical columns in the periodic table are called


The stclairdrake.netical actions of atoms is controlled by their electron configuration. Since the households of elements were organized by their stclairdrake.netical behavior, the is predictable the the individual members of every stclairdrake.netical family members will have similar electron configurations.


Families that the regular Table

Remember the Mendeleev i ordered it the periodic table for this reason that facets with the most comparable properties were placed in the exact same group. A group is a vertical shaft of the periodic table. Every one of the 1A aspects have one valence electron. This is what causes these elements to reaction in the same methods as the various other members that the family. The elements in 1A space all very reactive and kind compounds in the same ratios with similar properties with various other elements. Since of their similarities in your stclairdrake.netical properties, Mendeleev put these aspects into the very same group. Group 1A is likewise known as the alkali metals. Return most metals tend to be really hard, these metals are actually soft and can be quickly cut.

Group 2A is likewise called the alkaline planet metals. As soon as again, because of your similarities in electron configurations, these facets have comparable properties to every other. The exact same pattern is true of other teams on the regular table. Remember, Mendeleev i ordered it the table therefore that aspects with the most comparable properties to be in the same team on the regular table.

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

The noble gases room in group 8A. These elements also have comparable properties to every other, the most far-reaching property being the they are exceptionally unreactive, rarely creating compounds. Us will learn the reason for this later, once we comment on how compounds form. The elements in this team are additionally gases in ~ room temperature.

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

Summary

The upright columns top top the routine table are dubbed groups or families due to the fact that of their similar stclairdrake.netical behavior. All the members of a household of aspects have the same number of valence electron and comparable stclairdrake.netical properties. The horizontal rows ~ above the periodic table are referred to as periods.
