Are there the same number of electrons in the first four elements of the alkali family?
They all have a different electrons
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
How is the number assigned to a family related to the electron configuration of each element in that family?
The elements on the periodic table are arranged in periods and groups. The periods run across the table horizontally from left to right, whilst the groups run vertically from top to bottom. Elements from the same group tend to have similar chemical properties since they have the same number of electrons in their outer shells. :) You can find which elements are in which groups and more about the groups themselves by looking at a periodic table for the numbers above the columns or searching Google for "group 1" for example.
What is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
What chemical family has a group number 1A?
This is the alkali metals family.
What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
What is true about elements in the same period of the periodic table?
If they are placed in the same vertical column, which is called a group, it means that they have similar properties. For example, the first column (group) of the periodic table are the alkali metals. The second is alkali earth metals. Other groups include halogens, royal gases, etc.
Why are the alkali metals and the halogens among the reactive elements an the periodic table?
alkali metals have one valence electron and halogens have 7. since elements always want to have a full outer shell, these two types of elements react easily with each other to form a full outer shell of 8 electrons.
Why is the alkali metal more reactive that an alkaline earth metal?
the alkali metals have one valence electron, or one electron available to bond with another particle. this lets them bond easily with, lets say, a halogen, which has one 'slot' for an electron. two atoms of an alkali metal would be able to bond with a chalcogen, and so on. it's really all in the number of electrons. the alkaline earth metals have two valence electrons, so they would bond less easily with other elements.
How do the valence electron configurations of the alkali metals compare with others?
The valance electron configuration is the same in each at ns1 where n = the period number.
Why do all elements in group 1 react in similar way?
All elements in the same group (or column) in the periodic table have the same number of valence electrons and it is the number of valence electrons that determine the reactivity of most elements.See the Related Questions to the left for more information.
How do the valence electrons configurations of the alkali metals compare with each other?
The valance electron configuration is the same in each at ns1 where n = the period number.
