Among the options provided, the group that is likely to have similar chemical and physical properties is sodium, potassium, and rubidium.
This is because sodium (Na), potassium (K), and rubidium (Rb) are all alkali metals, found in Group 1 of the periodic table. Elements in the same group typically share similar characteristics due to their similar electron configurations. Alkali metals, for instance, are known for their high reactivity, especially with water, and they tend to form similar compounds.
On the other hand, the other groups consist of elements from various groups on the periodic table, leading to different properties. For example, boron, silicon, and germanium are metalloids but belong to different categories, while carbon, nitrogen, and oxygen represent nonmetals with distinct properties. Sodium, magnesium, and aluminum include both metals and can exhibit varying behaviors, and oxygen, sulfur, and chlorine are nonmetals from different groups as well.
