How many valence electrons does an atom of rubidium have?

Number of Electrons 37

To determine the number of valence electrons an atom of rubidium has, we need to look at its position on the periodic table. Rubidium (Rb) is in Group 1, also known as the alkali metals group.

Group 1 elements, like rubidium, have one valence electron. The number of valence electrons in an atom corresponds to the group number for elements in Groups 1 and 2. So, in this case, rubidium has one valence electron.

To find the number of valence electrons for an atom of a different element, simply locate the element on the periodic table and identify its group number.
