- SHELL /ʃel/ · noun, verb
- The outer covering of a tree seed, typically hard and woody. To remove the outer covering of something, especially a nut or a seed. Related: husk, peel, covering, exoskeleton.
- VALENCE /ˈvæləns/ · noun
- The capacity of an atom or radical to combine with others; the number of electrons an atom loses or gains to form a chemical bond. In chemistry, the valence of an atom is a measure of its combining power. Related: combining power, chemical affinity, electronegativity, oxidation state.
- BOND /bɒnd/ (UK), /bɑːnd/ (US) · noun (also verb)
- A bond is a strong connection or tie linking people, groups, or things, whether emotional, physical, or financial. In finance, it specifically means an interest-bearing security issued by a government or company as a way of borrowing money. Related: tie, connection, link, attachment.
