Question

Which element would you expect to behave most like sodium?

Responses

Ba
Mg
Rb
H

Answer 1

Rb

Step-by-step explanation:

Elements arranged in vertical column are part of family or a group. Elements in a group all act very similarly. Sodium falls in Group I which consists of both H and Rb. But you have to remember that H is non-metal whereas, Rb is metal (sodium is metal as well) thus Rb would be closest to sodium in behavior.
