Na = Rb Ne = Kr O = Se

Explanation:

According to modern periodic table, the elements present in same group have same chemical properties, because they same valence shell electrons.

Na and Rb:

As these both elements are present in group one, so these are called Alkali metals. Almost all alkali metal have same chemical properties.

Ne and Kr:

Both these elements are present in group 18, called as noble gases. They have same chemical properties like both are stable and are inert.

O and Se:

Both elements are present in group 16. Both have same chemical properties. Both have same valence shell electrons.
