Question

12. Which two elements have the most similar chemical properties?

Answer 1

Elements that have similar chemical properties are typically found in the same group (column) of the periodic table. For example, sodium (Na) and potassium (K) are both alkali metals in Group 1 and have very similar chemical properties, such as their reactivity with water and their formation of similar compounds. Similarly, chlorine (Cl) and fluorine (F) are both halogens in Group 17 and exhibit similar reactivity and properties within that group.
