* Find Bromine's Atomic Number: The atomic number of an element tells you how many protons it has. Bromine (Br) has an atomic number of 35.

* Add Two Protons: Two more protons than bromine would be 35 + 2 = 37 protons.

* Identify the Element: The element with 37 protons is rubidium (Rb).

Important Note: Atoms are electrically neutral. This means they have an equal number of protons (positive charge) and electrons (negative charge). So, if an atom has two more protons, it will also have two more electrons.
