Kr
Sometimes. There's nothing about the periods that makes such reactions either especially likely or especially unlikely. What groups the elements are in has more of an effect.
completely filled valence shells
Helium, neon and argon are the least likely elements to form compounds.
Group I elements (that is alkali metals)

Kr; Krypton

Either the enzyme has two distinct active sites, or the reactants involved in the two reactions are very similar in size and shape
Carbon.
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium all have an oxidation state of plus 2.
A pair of elements in the same group are more likely to have similar properties. This is why groups are also called families. In the main group elements, groups 1,2, 13-18, the elements in a group have the same numbers of valence electrons in their outermost energy levels. This accounts for the fact that they behave in a similar matter in chemical reactions.

Helium, neon and argon are the least likely elements to form compounds.
The light-dependent reactions will not occur.
