What kind of chemical bond is present in hydrogen compounds? What type of crystal lattice do they have? How does the polarity of the connection change by period and by group, main subgroup?

In hydrogen compounds there is a covalent polar bond, they have a molecular crystal lattice.
The polarity of a bond depends on the difference and EO – the larger it is, the more polar the bond is.
