offer the name and location of details groups top top the regular table, consisting of alkali metals, alkaline earth metals, noble gases, halogens, and transition metals. Define the relationship between the urbanbreathnyc.comical habits of family members in the regular table and also their electron configurations. Identify facets that will have the most similar properties to a offered element.

You are watching: Why do elements in the same group of the periodic table have similar properties?


The urbanbreathnyc.comical behavior of atom is regulated by your electron configuration. Because the family members of elements were arranged by your urbanbreathnyc.comical behavior, the is predictable the the individual members of every urbanbreathnyc.comical household will have similar electron configurations.


Families of the routine Table

Remember the Mendeleev i ordered it the periodic table for this reason that facets with the most comparable properties were inserted in the very same group. A group is a vertical tower of the routine table. All of the 1A aspects have one valence electron. This is what causes these elements to react in the same means as the other members that the family. The elements in 1A room all very reactive and type compounds in the very same ratios with comparable properties with other elements. Due to the fact that of their similarities in their urbanbreathnyc.comical properties, Mendeleev placed these facets into the same group. Group 1A is also known as the alkali metals. Although most metals tend come be really hard, these steels are actually soft and also can be easily cut.

Group 2A is likewise 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 every other. The very same pattern is true the other groups on the routine table. Remember, Mendeleev arranged the table therefore that facets with the most similar properties to be in the same group on the periodic table.

It is necessary to acknowledge a pair of other crucial groups ~ above the periodic table by their group name. Team 7A (or 17) elements are additionally called halogens. This group contains really reactive nonmetal elements.

The noble gases space in team 8A. These elements additionally have comparable properties to each other, the most significant property being the they are extremely unreactive, rarely forming compounds. We will find out the factor for this later, as soon as we talk about how compound form. The facets in this group are additionally gases at room temperature.

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

Summary

The upright columns on the regular table are referred to as groups or families because of their comparable urbanbreathnyc.comical behavior. Every the members of a household of elements have the same variety of valence electron and similar urbanbreathnyc.comical properties. The horizontal rows ~ above the periodic table are called periods.
