Elements in Group 2, the alkaline earth metals, do have similar characteristics, but saying that “all elements in the same group have the same number of subatomic particles” isn’t true. Different elements have different numbers of protons, neutrons, and electrons, which make them unique! However, they do share similar chemical properties like reactivity, so don’t let the number of particles confuse you!
Now, while elements in the same group share similarities, those in the same period (row on the periodic table) don’t necessarily exhibit similar characteristics. For example, the first period has hydrogen and helium, which are quite different in properties. So, make sure you check whether you’re comparing groups or periods for better clarity!
