||||
|---|---|---|---|---|---|
| Solid | particles vibrate in place, definite volume, definite shape, low energy state
🗑
|
||||
| Freezing | process by which a liquid changes into a solid, losing energy
🗑
|
||||
| Condensation | process by which a gas changes to a liquid, losing energy
🗑
|
||||
| Melting | process by which a solid changes into a liquid, gaining energy
🗑
|
||||
| Sublimation | process by which a solid changes into a gas without passing through the liquid phase, gaining energy
🗑
|
||||
| Liquid | Particles are free flowing, no definite shape, definite volume
🗑
|
||||
| Matter | anything that has mass and takes up space (volume)
🗑
|
||||
| Gas | Particles move to take up all available space, no definite shape or volume, high energy state
🗑
|
||||
| Vaporization | process by which liquid changes to a gas, gaining energy
🗑
|
||||
| Density | The measure of compactness or how much mass is in a particular volume
🗑
|
||||
| Proton | Positively charged particle in the nucleus of and atom.
🗑
|
||||
| Electron | Negativley charged particle that exists in an electron cloud formation around an atoms's necleus.
🗑
|
||||
| Neutron | Electrically neutral particle that has the same mass as a proton and is found in an atom's nucleus.
🗑
|
||||
| Atom | the smallest component of an element having the chemical properties of the element
🗑
|
||||
| Nucleus | central region of an atom, contains protons and neutrons, very dense
🗑
|
||||
| Compound | atoms of different elements join chemically; properties of compounds are different from properties of the individual elements they contain
🗑
|
||||
| Electon Cloud | area surrounding the nucleus of the atom, contains the electrons located in energy levels
🗑
|
||||
| Chemical Reaction | bonds in the original substances are broken and new bonds formed; this produces one or more different substances - evidence consists of an unexpected color change, a precipitate forming, bubbles/gas produced, odor or temperature change
🗑
|
||||
| Metal | At room temperature most metals are hard, shiny solids that can be bent without breaking; good conductors of heat and electricity
🗑
|
||||
| Nonmetal | At room temperature some nonmetals are solids that crack or break easily; others are gases. At room temperature nonmetals are not shiny and do not conduct heat or electricity very well.
🗑
|
||||
| Metalloid | have properties of metals and nonmetals;occur along the stairstep line
🗑
|
||||
| Physical Change | a substance changes but does not become a new substance example: water (liquid) freezing to become ice (solid)
🗑
|
||||
| Chemical Change | characteristics of a substance that are observed when it reacts (changes) to produce one or more different substances
🗑
|
||||
| Endothermic Reactions | Chemical reaction in which heat energy is absorbed: temperature decreases
🗑
|
||||
| Organic Compound | Most compounds that contain carbon, including nucleic acids, proteins, carbohydrates, and lipids.
🗑
|
||||
| Product | Substance that forms as a result of a chemial reaction.
🗑
|
||||
| Reactant | Substance that exists before a chemical reaction begins.
🗑
|
||||
| Specific Heat | the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree C
🗑
|
||||
| Atomic Mass (mass number) | the number of protons + the number of neutrons in the nucleus
🗑
|
||||
| Atomic Number | the number of protons in the nucleus
🗑
|
||||
| Exothermic Reactions | Chemical reaction in which heat energy is released: temperature increases
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
