why do Na and K have similar chemical properties?
What's 1 risk with the use of radium?

Na and Rb are inn the same group (alkali metals) so they would be the closest

Na and Rb. They are in the same group of the periodic table so react in similar ways. Even though Na and Ar are closer on the periodic table they are very different due to sodium only having 1 electron in it's outer shell and argon having a full compliment of 8. As is very different to the others so is right out of the question.

Check on the periodic table Rb and Na are in the same colum so they are the most chemically similar and both will react to the same substances.

Na and Rb, because they are in the same column on the periodic table.

2. Mg, Ca and Ba. They are both in the group 2. Groups are based on the chemical reactions. Always look for elements in the same group. (Groups are the vertical columns)
