Hydrogen Bonds

Weak bonds that form between a hydrogen atom in one molecule and a more electronegative atom, such as oxygen or nitrogen, in another, playing critical roles in the structure of DNA and proteins.

Ionic Bonds

Ionic bonds are chemical bonds formed between two atoms when one atom transfers electrons to another, resulting in oppositely charged ions that attract each other.
