||||
|---|---|---|---|---|---|
| show | a substance that cannot be broken down to other substances by chemical reactions
🗑
|
||||
| Mass numeber | show 🗑
|
||||
| show | Atoms of the same element with a different number of neutrons
🗑
|
||||
| show | A subatomic particle with a single negative electrical charge and a mass about 1/2,000 of that of a neutron or proton; one or more move around the nucleus of an atom
🗑
|
||||
| Valence shell | show 🗑
|
||||
| GN Lewis | show 🗑
|
||||
| show | anything that has mass and takes up space
🗑
|
||||
| show | a substance consisting of two or more different elements combined in a fixed ratio
🗑
|
||||
| essential elements | show 🗑
|
||||
| show | an element indispensable for life but required in extremely minute amounts
🗑
|
||||
| show | the smallest unit of matter that retains the properties of an element
🗑
|
||||
| neutrons | show 🗑
|
||||
| show | A subatomic particle with a single positive electrical charge, with a mass of about 1.7 x 10^-24g, found in the nucleus of an atom.
🗑
|
||||
| atomic nucleus | show 🗑
|
||||
| show | A measure of mass for atoms and subatomic particles; the same as the atomic mass unit, or amu
🗑
|
||||
| atomic number | show 🗑
|
||||
| mass number | show 🗑
|
||||
| show | the total mass of an atom, which is the mass in grams of 1 mole of the atom
🗑
|
||||
| show | one of several atomic forms of an element, each with the same number of protons but a different number of neutrons, thus differing in atomic mass
🗑
|
||||
| show | an isotope (an atomic form of a chemical element) that is unstable; the nucleus decays spontaneously, giving off detectable particles and energy
🗑
|
||||
| energy | show 🗑
|
||||
| show | The energy that matter possesses as a result of its location or spatial arrangement (structure).
🗑
|
||||
| electron shells | show 🗑
|
||||
| show | An electron in the outermost electron shell
🗑
|
||||
| show | The outermost energy shell of an atom, containing the valence electrons involved in the chemical reactions of that atom
🗑
|
||||
| show | The three-dimensional space where an electron is found 90% of the time
🗑
|
||||
| chemical bonds | show 🗑
|
||||
| covalent bond | show 🗑
|
||||
| show | Two or more atoms held together by covalent bonds
🗑
|
||||
| single bond | show 🗑
|
||||
| double bond | show 🗑
|
||||
| valence | show 🗑
|
||||
| electronegativity | show 🗑
|
||||
| show | a type of covalent bond in which electrons are shared equally between two atoms of similar electronegativity
🗑
|
||||
| show | a covalent bond between atoms that differ in electronegativity; the shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive
🗑
|
||||
| show | an atom or group of atoms that has gained or lost one or more electrons, thus acquiring a charge
🗑
|
||||
| cation | show 🗑
|
||||
| anion | show 🗑
|
||||
| show | a chemical bond resulting from the attraction between oppositely charged ions
🗑
|
||||
| ionic compounds/salts | show 🗑
|
||||
| show | a type of weak chemical bond that is formed when the slightly positive hydrogen atom of a polar covalent bond in one molecule is attracted to the slightly negative atom of a polar covalent bond in another molecule or in another region of the same molecule
🗑
|
||||
| show | Weak attractions between molecules or parts of molecules that result from transient local partial charges
🗑
|
||||
| show | the making and breaking of chemical bonds, leading to changes in the composition of matter
🗑
|
||||
| show | a starting material in a chemical reaction
🗑
|
||||
| products | show 🗑
|
||||
| show | in a chemical reaction, the state in which the rate of the forward reaction equals the rate of the reverse reaction, so that the relative concentrations of the reactants and products do not change with time
🗑

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.
