ChemisTRY

3. Refers to the way in which atoms bond with each other.
6. Molecules with the same chemical formula but different chemical structures.
8. Electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom.
10. Weakest intermolecular force.
12. Sharing of an electron pair between two atoms.
16. Describes the ability of an atom to attract electron towards itself in a covalent bond.
17. Process of a substance spreading out to evenly fill its container or environment.
18. The number of constituent particles that are contained in one mole.
19. Pressure and volume are inversely proportional at constant temperature.
21. It is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol).
22. Transfer of valence electrons between atoms.
23. Pressure and temperature are directly proportional at constant volume.

1. It is composed of two atoms, chemically bonded together.
2. Unsaturated hydrocarbon containing at least one carbon—carbon triple bond.
4. Forces that exist between molecules.
5. The SI unit for the amount of a substance.
7. The rate of a gas is inversely proportional to the square root of the mass of its particles.
9. Attractive forces between polar molecules.
11. A compound of hydrogen and carbon, such as any of those which are the chief components of petroleum and natural gas.

14. Average mass of atoms of an element, calculated using the relative abundance of isotopes in a naturally-occurring element.
15. Temperature and volume are directly proportional at constant pressure.
20. It consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
