Vocabulary of Chemistry

1. Electrolysis is dissociating an electrolyte into an ion on the electrode in the presence of an electric current. Electrical conduction through an electrolyte solution will result in a chemical change.
2. Matter is everything that occupies space and has mass. As the universe is composed of matter, tables, chairs and air we normally breathe is one included into the material.
3. Element is a substance that can not be changed into a simpler form under normal or normal laboratory conditions. In other words, the element is a pure substance that can not be deciphered into a simple substance through a chemical reaction.
4. The compound is a single substance consisting of two or more elements which can be broken down into simpler forms through chemical reactions.
5. Benzene, also known as the chemical formula C6H6, PhH, and benzol, is an organic chemical compound that is colorless and flammable liquid and has a sweet smell.
6. Bases are the opposite of acids, ie they are intended for elements / chemicals having a pH greater than 7.
7. Acid is a substance that can give protons (H + ions) to other substances (called bases), or can accept free electron pairs of a base.
8. Suspension is heterogeneous mixture containing a liquid where visible particles settle.
9. Compound is a substance in which the atoms of 2 or more elements are combined.
10. Heterogeneous Mixture is mixture in which different materials can easily be distinguished.
11. Homogeneous Mixture is contains 2 or more gases, liquids, or solids substances blended evenly.
12. Solution is homogeneous mixture with particles so small that they cannot be seen with a microscope.
13. Colloid is type of mixture with particles that are larger than those in solutions, but not heavy enough to settle out.
14. Tyndall Effect is scattering of light by colloidal particles.
15. Distillation is a process for separating substances by evaporating a liquid and recondensing its vapor.
16. Chemical Property is characteristic of a substance that indicates whether it can undergo a chemical change.
17. Chemical Change is a change of one substance to another.
18. Kinetic Theory is explanation of how particles in matter behave.
19. Melting Point is the point in temperature when the solid starts to liquefy.
20. Heat of Fusion is the energy required to change a substance from a solid to a liquid at its melting point.
21. Boiling Point is the point in temperature when the liquid starts to boil.
22. Heat of Vaporization is amount of energy required for a liquid to become a gas.
23. Diffusion is spreading of particles throughout a given volume until they are distributed.
24. Buoyancy is ability of a fluid to exert an upward force on an object immersed in it.
25. Nucleus is the center of a atom.
26. Protons is particles in a atom with a positive charge.
27. Neutrons is  particles in a atom with no charge.
28. Electrons is particles in a atom with a negative charge.
29. Quarks is smaller particles in neutrons and protons.
30. Electron Cloud is area around a nucleus where electrons are mostly found.
31. Atomic Number is number of protons in an atom is equal to a number called {blank}.
32. Mass Number is this number is the sum of the number of protons and neutrons.
33. Isotopes is atoms of the same element that have different numbers of neutrons.
34. Average Atomic Mass is the weighted average mass of its isotopes.
35. Periodic Table is a table filled with elements in order of atomic numbers, etc.
36. Groups is the vertical columns in the periodic table.
37. Electron Dot Diagram is uses the symbol of the element and dots to represent electrons.
38. Nonmetals is usually gasses or brittle solids at room temperature.
39. Diatomic Molecule is consists of 2 atoms of the same element in a covalent compound.
40. Sublimation is the process of a solid going directly into a vapor.
