ionic bond: between a metal and a nonmetal
Covalent bond: between 2 non metals USUALLY
and i don't know about hydrogen bonds...
It is covalent due to the small electronegativity difference between hydrogen and sulfur.
The bond between hydrogen and oxygen is covalent.
HBr is covalent as the difference in electronegativity between the two atoms is less than 1.7
Fluorine atoms have a covalent bond between each other to form a covalent molecule. Fluorine bonded to a metal will have ionic bonds. Fluorine bonded to a non-meatl will have polar covalent bonding.
The difference of electronegativity between hydrogen and phosphorus is not adequate to form ionic bonds.

The bonds between calcium and hydroxide in calcium hydroxide are ionic, and the bonds between oxygen and hydrogen are covalent.
It is covalent as there is not enough of a difference in electronegativity for the fluorine to completely pull the electrons away from hydrogen.
When talking about ionic or covalent, we are referring to the bonds between two atoms or ions, not characterizing the whole molecule. In hydrogen peroxide, the link between the two oxygen atoms is a covalent bond (both atoms are negatively charged, and share an electron), while the link between the hydrogen and oxygen atoms is an ionic bond (the oxygen atom is negatively charged and the hydrogen is positively charged, thus they are attracted to each other). ^^^ionic means that the electronegativity difference between atoms is greater than 1.5. Oxygen and hydrogen have a difference less than 1.5 but greater than .5 which makes it polar. Hydrogen peroxide is a covalent compound
The bond between hydrogen and fluorine is not a covalent bond. When hydrogen bonds with oxygen, nitrogen, or fluorine, then it is called a hydrogen bond. Hydrogen bonds will be stronger than a regular covalent bond, so the electronegativity difference will be higher.
The ionic bond bond is based on electrostatic attraction between ions.The covalent bond is based on electrons sharing between two atoms.The hydrogen bond exist between two polar groups and is a weak bond.

Sodium hydroxide is an ionic compound which disassociates in to Na+ and OH- ions in solution.
