WebApr 8, 2024 · In physical chemistry, foam or foam spray is defined as a colloidal system (it means a dispersion of particles in the continuous medium), where the particles are given as gas bubbles and the medium as a liquid. The word is often used to describe a lightweight rigid or spongy cellular material. Types of Foams WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl. Sodum is a cation (lost an electron and became positive) and chlorine is an anion (gained an electron and becomes negative) in this situation.
