How many valence electrons does an atom of rubidiun have? A)One B)Five C)Six D)37
one valence electron
To determine the number of valence electrons in an atom of rubidium, you need to look at its electron configuration in the periodic table.
Rubidium (symbol: Rb) is located in Group 1 or the alkali metals group of the periodic table. The group number represents the number of valence electrons an atom of that element has.
In the case of rubidium, it is located in Group 1, which means it has 1 valence electron. Therefore, the correct answer is A) One.
