Question

Using the Periodic Table, predict which elements will have similar chemical properties or reactivity.
A
Cadmium, calcium, and carbon
B
Magnesium, strontium, and barium
C
Rubidium, yttrium, and zirconium
D
Nitrogen, sulfur, and bromine

Answer 1

To identify which set of elements will have similar chemical properties or reactivity, we can refer to their positions in the Periodic Table and their group classifications.

A. **Cadmium, calcium, and carbon** - These elements belong to different groups: cadmium (group 12), calcium (group 2), and carbon (group 14). They are not likely to have similar properties.

B. **Magnesium, strontium, and barium** - These elements are all alkaline earth metals, located in group 2 of the Periodic Table. They have similar chemical properties and reactivity.

C. **Rubidium, yttrium, and zirconium** - Rubidium is an alkali metal (group 1), while yttrium and zirconium are transition metals (group 3). They are not in the same group and do not have similar properties.

D. **Nitrogen, sulfur, and bromine** - These elements belong to different groups: nitrogen (group 15), sulfur (group 16), and bromine (group 17). They do not share similar properties.

Based on this analysis, the correct answer is:
**B. Magnesium, strontium, and barium** - They are all alkaline earth metals and will have similar chemical properties and reactivity.
