|---|---|---|---|---|---|
| proton | positively charged and possesses a mass of one atomic mass unit (amu), is located within the nucleus of the atom
🗑
|
||||
| neutron | occupies a position within the atom’s nucleus. They possess no charge (neutral) and have a mass of 1 amu
🗑
|
||||
| atomic mass | The sum of the number of protons and the number of neutrons inside the nucleus of an atom constitutes the atom’s atomic mass
🗑
|
||||
| isotope | has the same atomic number but differs in atomic mass
🗑
|
||||
| electron | negative charge and contribute essentially nothing to the atomic mass of the atom. They are positioned at various levels around an away from the nucleus.
🗑
|
||||
| Electrovalent or ionic bond | Results when the atoms of two or more elements combine with each other by transferring electrons
🗑
|
||||
| rule of 8 | The tendency in nature is for all atoms to seek 8 electrons in the outermost electron shell
🗑
|
||||
| Ion | charged bodies that have lost or gained electrons
🗑
|
||||
| Cation | substance that has lost an electron
🗑
|
||||
| Anion | substance that has gained electron
🗑
|
||||
| Covalent bonds | Result from the sharing of one or more pairs of electrons
🗑
|
||||
| Kinetic Theory of Matter | states that any given sample of matter is composed of many small particles (molecules, atoms, or ions) that are in constant motion.
🗑
|
||||
| van der Waals forces | the forces between adjacent molecules, limit the mobility of molecules in a solid
🗑
|
||||
| liquids | molecules are free to move about within the confines of the container
🗑
|
||||
| Define Pressure | quantitatively defined as a force (F) acting perpendicularly to a surface area (A) or P = F / A
🗑
|
||||
| Acid | a substance that releases hydrogen ions (H+), or donates protons. A substance that increases the hydrogen ion concentration of a solution.
🗑
|
||||
| Base | a compound that provides hydroxyl ions (OH-)
🗑
|
||||
| acidic | Solutions that have greater amounts of H+ ions, as compared to the number of OH- ions
🗑
|
||||
| alkaline | Solutions having a greater concentration of OH- ions relative to their H+ concentration
🗑
|
||||
| The mathematical expression indicating pH | -log [H+]
🗑

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.
