The yellowcomic.comical behavior of atom is managed by your electron configuration. Since the families of elements were arranged by your yellowcomic.comical behavior, the is predictable that the separation, personal, instance members of every yellowcomic.comical family will have similar electron configurations.
Families the the regular Table
Remember the Mendeleev arranged the routine table so that elements with the most comparable properties were placed in the same group. A group is a vertical pillar of the routine table. All of the 1A aspects have one valence electron. This is what reasons these facets to reaction in the same methods as the other members the the family. The facets in 1A room all an extremely reactive and type compounds in the very same ratios with similar properties with other elements. Due to the fact that of their similarities in their yellowcomic.comical properties, Mendeleev put these elements into the very same group. Group 1A is additionally known together the alkali metals. Back most steels tend to be really hard, these steels are in reality soft and also can be easily cut.
Group 2A is additionally called the alkaline planet metals. When again, since of their similarities in electron configurations, these facets have similar properties to every other. The exact same pattern is true the other groups on the periodic 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 essential to identify a couple of other crucial groups on the regular table by their group name. Team 7A (or 17) aspects are likewise called halogens. This group contains very reactive nonmetal elements.
The noble gases space in team 8A. This elements also have comparable properties to every other, the most far-ranging property being that they are exceptionally unreactive, rarely developing compounds. Us will find out the factor for this later, once we comment on how compound form. The elements in this group are additionally gases in ~ room temperature.
If you have the right to locate an aspect on the periodic Table, you have the right to use the element"s place to number out the energy level of the element"s valence electrons. A period is a horizontal heat of aspects on the regular table. For example, the elements sodium ((ceNa)) and also magnesium ((ceMg)) space both in period 3. The aspects astatine ((ceAt)) and also radon ((ceRn)) space both in duration 6.
