Fluorine has the most negative charge when it is bonded with hydrogen, rather than any other element in the Periodic Table.
ions
In a covalent bond neither group of atoms would gain any charge since the electrons are "shared" between two atoms.
Hydrogen chloride (HCl) is a polar covalent molecule because it has a significant difference in electronegativity between the hydrogen and chlorine atoms. Chlorine is more electronegative, meaning it has a stronger attraction for electrons, causing the shared electron pair between hydrogen and chlorine to be unequally shared. As a result, the chlorine atom acquires a partial negative charge, while the hydrogen atom acquires a partial positive charge. This uneven distribution of charge creates a dipole moment, making HCl a polar covalent molecule.

a positive charge caused by a covalent bond with oxygen

A negative charge exists because of the electronegativity of oxygen.
Check the electronegatviies of the atoms. The highest from the top are fluorine, oxygen, chlorine and nitrogen. The highest electronegativity pulls the electrons in the bond closest, gets the most negative charge.

Hydrogen bonds and covalent bonds are two completely different things. Covalent bonds share an electron, while hydrogen bonds (just for water molecules) act like magnets- the Oxygen atom has a slight negative charge and it "attracts" the Hydrogen atoms, which have a slight positive charge.
A negative charge that exists because of a covalent bond with hydrogen
Because of the unequal sharing of electrons. As in H2O, Hydrogen has a positive charge and Oxygen has a negative charge.
O, being most electronegative acquires the most negative charge in a covalent bond with hydrogen
Hydrogen is linked by a covalent bond to an atom of oxygen. The covalent bonds are polar, as the oxygen atoms have a slight negative charge.
