Definitions:

Electrons

Subatomic particles with a negative charge, orbiting the nucleus of an atom and involved in chemical bonds and electricity.

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.

Covalent Bonds

Covalent bonds are chemical bonds where atoms share pairs of electrons, enabling each atom to attain a stable electron configuration.
