Memorize them, there are only three, Nitrogen, Oxygen, and Fluorine.
Hydrogen bonding in water molecules exists due to the large electronegativity difference between hydrogen and oxygen, allowing a strong dipole-dipole interaction. Hydrogen sulfide lacks this strong electronegativity difference between hydrogen and sulfur, resulting in weaker van der Waals forces instead of hydrogen bonding.
FONFlorineOxygenNitrogenThe hydrogen must be bonded to one of these highly electronegative atoms to participate in hydrogen bonding.HClChlorine is not of this group shown above. Do you know why?
Peptide bond is a covalent bond. Covalent bonds are stronger than hydrogen bonds. Think of electrons as the glue of a molecule. A covalent bond has electron interaction uniformity(They're glue is pretty consistent between two atoms). Now hydrogen bonds don't have as much glue; think of it as a few smeared drops of glue. So why do they have not as much glue(a weaker interaction than peptide bonds)? That's because Hydrogen bonds have hydrogens bonded to an electronegative atom(that means they like electrons). An example of an electronegative atom would be oxygen. Oxygen(or any given electronegative atom) will briefly take hydrogen's only electron when they pair up. So hydrogen's electron spends more time around the oxygen because it takes longer to circle around oxygen due to it being bigger than hydrogen. We know electrons have negative charge, so what happens when hydrogen's electron is over near the oxygen? Hydrogen gets a partial positive charge, and oxygen gets a partial negative charge!
All of the elements, apart from the transition metals in the middle, are divided into groups. Group 1 elements have 1 electron in their outer shell, and this is the electron used in bonding. Group 2 have 2 electrons, Group 3 elements have 3, and so on. Group 8 elements have a full outer shell, so they generally don't react.
Elements in the third period or below on the periodic table, such as sulfur, phosphorus, and chlorine, do not always follow the octet rule because they can accommodate more than eight electrons in their valence shell due to the availability of d-orbitals for bonding. Additionally, elements like boron and beryllium can form stable compounds with fewer than eight electrons.

There are a few types of hydrogen bonds. Fluorine, oxygen, and nitrogen are the elements that typically form bonds with hydrogen.
"H" or Hydrogen is an element, there are no other elements in it because all elements are pure substances.
Alkali Metals, except for Hydrogen, which is a Nonmetal.

Well I believe there is approximately about 60 elements in the sun but I do know 2 of them--hydrogen and helium. ___________________________ The Sun is 70% hydrogen, 28% helium and 2% "other elements" .

The chemical formula of water is H2O: hydrogen and oxygen, if you want to know this.
You have three elements in carbohydrates. Carbon, hydrogen and oxygen. It is interesting to know the composition of the glucose. When two molecules of glucose that get attached to each other, you get one molecule of water out.
