Answer:
four
Explanation:
We know that hydrogen atoms have a valency of 4, this means that these atoms can bond with 4 other atoms.
Actually, the maximum number of bonds for an atom equals the number of electrons in the full valence shell, minus the number of valence electrons.
The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons.
Hydrogen has 8 electrons in its full valence shell and it has 4 valence electrons. Therefore, it can bond with 8 - 4 = 4 other atoms
