Rubidium, classified as an alkali metal, possesses 1 valence electron. The valence electrons of rubidium can be identified by its position on the periodic table or by looking at its electron configuration.
Methods
Using periodic table
Get the periodic table having the chemical elements marked on it as mentioned above.
Now mark the location of rubidium on the periodic table.
Next, mark the group number of rubidium on the periodic table.
The valence electrons of each main-group element can be determined by the column in which it is located.
(i.e., all group 1 elements have 1 valence electron, all group 2 elements have 2 valence electrons, skip the transition metals… then, all group 13 elements have 3 valence electrons, all group 14 elements have 4 valence electrons, and so on up to group 18 elements)
Since rubidium is in group 1, it has 1 valence electron.
Using electron configuration
- First, write electron configuration of rubidium
The electron configuration of rubidium is [Kr] 5s1.
- Second, find highest energy level in electron configuration
In the above electron configuration, the highest energy level (5) is marked with green color.
- Finally, count electrons of that energy level
The 5th energy level contains 5s subshell and it has 1 electron. So rubidium has a total of 1 valence electron.
