The elements will have similar chemical properties or reactivity are; magnesium, strontium, and barium.
The question is incomplete, the complete question is;
Using the Periodic Table predict which elements will have similar chemical properties or reactivity.
Group of answer choices
rubidium, yttrium, and zirconium
nitrogen, sulfur, and bromine
magnesium, strontium, and barium
cadmium. calcium, and carbon
The periodic table has elements arranged in groups and periods. The elements in the same period has the same number of shells.
The elements in the same group has the same number of valence electrons. Remember that the reactivity of the elements is dependent on the valence shell.
So, the elements in the same group among the options are; magnesium, strontium, and barium.
These elements listed above will all have similar chemical properties or reactivity.
