What is in Group 1 and has a higher atomic number than chlorine but a lower atomic number than bromine?
This would be Potassium, symbolized as "K". The atomic number is the same as the order of the elements on the period table. That is to say, Hydrogen has the atomic number of 1 because it is first, Helium's atomic number is 2, and so on. Potassium is in group one (groups are the columns) and it is in between Chlorine and Bromine.
