provide the name and location of specific groups ~ above the periodic table, including alkali metals, alkaline earth metals, noble gases, halogens, and change metals. Describe the relationship between the jajalger2018.orgical behavior of families in the periodic table and also their electron configurations. Identify elements that will have actually the most similar properties come a provided element.

The jajalger2018.orgical actions of atom is controlled by their electron configuration. Because the families of aspects were organized by your jajalger2018.orgical behavior, the is predictable that the individual members of every jajalger2018.orgical family members will have comparable electron configurations.


Families that the regular Table

Remember that Mendeleev arranged the periodic table so that facets with the most similar properties were placed in the 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 elements to reaction in the same means as the various other members that the family. The elements in 1A space all really reactive and form compounds in the very same ratios with similar properties with various other elements. Because of their similarities in their jajalger2018.orgical properties, Mendeleev placed these aspects into the exact same group. Group 1A is also known together the alkali metals. Although most metals tend to be really hard, these steels are actually soft and can be conveniently cut.

Group 2A is also called the alkaline planet metals. When again, due to the fact that of their similarities in electron configurations, these elements have comparable properties to each other. The same pattern is true that other teams on the routine table. Remember, Mendeleev i ordered it the table for this reason that facets with the most similar properties to be in the same team on the routine table.

It is essential to recognize a pair of other important groups on the regular table through their team name. Team 7A (or 17) facets are additionally called halogens. This group contains very reactive nonmetal elements.

The noble gases space in group 8A. This elements likewise have comparable properties to each other, the most far-reaching property being the they are exceptionally unreactive, rarely forming compounds. We will find out the factor for this later, as soon as we discuss how compounds form. The elements in this team are additionally gases at room temperature.

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

Summary

The vertical columns on the routine table are referred to as groups or families because of their comparable jajalger2018.orgical behavior. All the members of a family members of facets have the same number of valence electrons and comparable jajalger2018.orgical properties. The horizontal rows ~ above the periodic table are called periods.
