Answer: Y is Hydrogen.

Explanation: Based on the valence electrons, X and Y are Group 1 Elements and Y is a Halogen. Based on the differences between X and Y and the similarities between Y and Z, we can say that Y is Hydrogen, the only nonmetal with 1 valence electron. This is based on the fact that it has typical nonmetal characteristics: low melting and boiling points.
