Question

Which of these groups of metal would have the most similar properties?. a. Ag, Au, Cu, Zn. b. Cr, Fe, Co, Ni. c. Al, Si, P, S. d. Mg, Ca, Sr, Ba

Answer 1

D. Mg, Ca, Sr, Ba

Step-by-step explanation:

Elements in the same group in the periodic table very often show a lot of similarity in physical properties and chemical properties. So in this case, the most probable answer would be D. Magnesium, Calcium, Strontium and Barium are going to share a lot of similar properties that the other group of elements are less likely to share.

Answer 2

The correct answer is letter (d.) Mg, Ca, Sr, Ba

These four elements are found in Group 2 of the periodic table, which are alkaline metals, therefore they have the very similar properties because of their 2 valence electrons, which makes them reactive.
