1. Chemical Compounds Vocabulary

2. bent shape Molecules with a ___ shape are tricky because they may appear linear from certain angles.

3. covalent bond A ____ bond is formed when the atoms in a compound are sharing 2 or more pairs of electrons (can be single, double or triple and polar or nonpolar).

4. crystalline structure Typically, ionic compounds have a ____ structure (form crystals), which although they may have color, they are brittle, transparent and grow in tiny block like groups.

5. double bond A ____ is formed when 4 electrons are shared in a bond.

6. ductility ____ is the ability to draw metal into wire.

7. electrical conductivity ___ is the ability of a substance to transfer electricity (the flow of electrons).

8. electron pair geometries ___ are the shapes that molecules take under the VSEPR theory.

9. electronegativity ____ is the tendency for an atom to attract electrons to itself when it is chemically combined with another element.

10. hydrogen bond A ______ or 'bridges' are the weak attraction between the positive and negative end of a polar molecule, such as the Hydrogen and Oxygen in water.

11. ionic bond The ___ is referred to as the electrostatic attraction that binds oppositely charged ions together.

12. Lewis Dot Structure A _____ is used to depict how a compound is formed between atoms.

13. linear shape ___ molecules have their atoms in a line.

14. malleability _____ is the ability of metal to be shaped or flattened.

15. metallic bond A _____ is the attraction between positive ions and surrounding mobile electrons.

16. molecules All compounds are ____, which are 2 or more different atoms bonded together.

17. non-polar bond A ____ is formed when the atoms in a compound are sharing (covalent bond) the electrons evenly.

18. polar bond A _____ is formed when one or more pairs of electrons are shared (making it covalent) unequally.

19. polar molecule A ____ molecule must have polar bonds with a positive and negative end, with a shape that has a positive and negative end like a tiny magnet.

20. representative unit _____ refers to the species present in a substance - usually atoms, molecules, or formula units (ions) - it’s the smallest we can get and still have the same properties of our sample.

21. shared electrons ___ are found inside of a covalent bond.

22. single bond In a _____, a single pair of electrons is shared between 2 atoms.

23. tetrahedral shape The ___ looks like a 4 point star or plus sign molecule, with 4 single bonds.

24. thermal conductivity ___ is the ability of a substance to transfer heat energy.

25. trigonal planer Molecules with a ___ shape contain a double bond.

26. triple bond In a ____, 6 electrons are shared between 2 atoms.

27. unshared pairs The pairs of electrons that are around an atom, but not part of a bond, are called ___.

28. VSEPR theory ____ explains why compounds form the same shapes every time they form, because the positive and negative parts are pushing and pulling against each other like tiny magnets, so they become electrostatically balanced. Stands for VALENCE SHELL ELECTRON PAIR REPULSION
