| Term | Definition |
|---|---|
| Scientific Notation | Scientific notation is the way that scientists easily handle very large numbers or very small numbers. |
| Percent Error | When you calculate results that are aiming for known values, the percent error formula is useful tool for determining the precision of your calculations. |
| Significant Figure | Each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit. |
| Quantitative Data | Quantitative data are measures of values or counts and are expressed as numbers. |
| Qualitative Data | Qualitative data are measures of 'types' and may be represented by a name, symbol, or a number code. |
| Chemistry | Chemistry is the scientific discipline involved with compounds composed of atoms |
| Isotope | Isotopes are variants of a particular chemical element which differ in neutron number. |
| Nuclear Fusion | A nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy. |
| Atomic Number | the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table. |
| Specific Heat | the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree). |
| Accuracy | |
| Precision | Precision is a description of random errors, a measure of statistical variability. |
| Precipitate | Precipitation is the creation of a solid from a solution. |
| Noble Gas | The noble gases make up a group of chemical elements with similar properties |
| Electron Cloud | It is used to describe where electrons are when they go around the nucleus of an atom. |
| Atom | An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. |
| Mass Number | the total number of protons and neutrons in a nucleus. |
| Density | The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. |
| Metalloid | an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. They are electrical semiconductors. |
| Mass Number | the total number of protons and neutrons in a nucleus. |
