Question

Hydrogen and halogen exist as molecules

Answer 1

Explanation:

Reaction with Hydrogen

All the halogens react directly with hydrogen, forming covalent bonds and—at sufficient levels of purity—colorless gases at room temperature. Hydrogen reacts with fluorine, chlorine, bromine, and iodine, forming HF, HCl, HBr, and HI, respectively

Answer 2

Answer:

H is the hydrogen atom involved in hydrogen bonding, and X is the halogen atom involved in halogen bonding. ... In both types of bonding, an electron donor/electron acceptor relationship exists. The difference between the two is what species can act as the electron donor/electron acceptor.
