Which element has similar chemical properties to Ba?
Ra
Rn
Sr
The element that has similar chemical properties to Ba (barium) is Ra (radium). Both Barium (Ba) and Radium (Ra) belong to Group 2 of the periodic table, also known as the alkaline earth metals. These elements have similar chemical properties due to their similar electronic configurations and placement in the periodic table.
To determine which element has similar chemical properties to Ba (barium), you can refer to the periodic table of elements. Ba belongs to Group 2, which is also known as the Alkaline Earth Metals group. The elements in this group share similar chemical properties due to the presence of two valence electrons in their outermost energy level.
Looking at the periodic table, we see that Ra (radium) is located directly below Ba. Elements in the same group tend to have similar chemical properties, so Ra is the element that has similar chemical properties to Ba.
On the other hand, Rn (radon) is not located in the same group as Ba and does not have similar chemical properties. Rn is a noble gas and belongs to Group 18, which has completely filled valence electron shells, making its chemical properties quite different from that of Ba.
