- 3. Compound A compound made up of only two different type of atoms.
- 7. Compound a chemical compound in which ions are held together by ionic bonds; compound made of metallic and non-metallic atoms.
- 9. Formula a formula giving the proportions (or simple ratio) of the elements present in a compound but not the actual numbers or arrangement of atoms.
- 12. bond a covalent bond in which each atom shares two electron; represented by an equal sign connecting two atoms.
- 13. covalent bond Bond between two non-metallic atoms by sharing electrons in which electrons are not shared equally.
- 15. point Constant temperature at which a liquid becomes vapor or gas.
- 18. An ionic substance that conducts electricity in aqueous (water) solution.
- 20. A crystal is a substance in which the constituent atoms, molecules, or ions are packed in a regularly ordered, repeating three-dimensional pattern.
- 21. bond Force of attraction between oppositely charged ions.
- 25. bond a covalent bond in which each atom shares two electron; represented by 3 lines connecting two atoms.

- 4. Atom or group of atoms with a positive or negative charge
- 5. point Constant temperature at which a solids becomes a liquid.
- 6. bond a covalent bond in which each atom shares only one electron; represented by a line connecting two atoms.
- 8. bond Force of attraction between atoms ions or molecules that enables the formation of a compound.
- 10. Ability of a substance to conduct electricity or to allow electrons or charges flow through it.
- 11. bond Force of attraction between two atoms of same or different metal.
- 14. compound A compound made of two or more nonmetal atoms bond by sharing valence electrons.
