7

Explanation:

A hydrogen atom has 1 outer electron, #1s^1#. That means that it needs one electron to complete the s orbital (it's outer shell).

Since #Y# has 7 valence electrons, this means that it can complete the outer shell of 7 hydrogen atoms. So a maximum of #7# hydrogen atoms can bond to #Y#
