Elements in the same group as zinc would be expected to have similar properties.
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
Magnesium, calcium, strontium, barium and radium have similar properties to beryllium. All the elements in group two of the periodic table have the same or similar properties. This is because they have the same number of electrons in their outermost shell.
Magnesium, strontium , and barium belong to group 2A of the periodic table. These have two valence electrons in their outermost shell. So these three elements have similar chemical properties. But the other given elements do not lie in same group so they have different chemical properties.

thorium and plutonium
Calcium shares properties with Magnesium and Strontium.
plutonium, and heluim
Elements in the same group as zinc would be expected to have similar properties.
1 and 2
Fluorine and Bromine are the two elements having the same property as that of Chlorine.
There is no fully objective answer to this question. Many chemists would consider that two lanthanide elements with atomic numbers differing by only one would be likely to qualify. Another possibility is the pair zirconium and hafnium. These are very similar in most chemical characteristics but differ greatly in electron capture tendencies in nuclear reactors.
chronium, tungsten, and seaborgium
potassium and chlorine
No, they're about as different as it's possible for two elements to be.
All elements have same number of valence electrons (two) and hence they have similar reactivity and chemical properties.
