Sodium and potassium belong to the same group of the Periodic Table. This is because?
- both are metals
- both are soft and lighter than water
- both form cations by losing electrons
-
both have identical electronic configuration
- both react with water vigorously
The correct answer is: D
Explanation
\(_{11}\)Na = 2 8 1
\(_{19}\)K = 2 8 8 1
Both have one electron in their outermost shell( similar electronic configuration). hence they are found in the same group of the periodic table. They both lose an electron to form cations but that is not the reason why they are in group one.
