ATOMS
| Term | Definition |
|---|---|
| ATOM | THE SMALLEST UNIT OF AN ELEMENT THAT RETAINS THE PROPERTIES OF THAT ELEMENT |
| CHEMICAL BOND | THE FORCE THAT HOLDS TWO ATOMS TOGETHER |
| CHEMICAL CHANGE | A CHANGE IN MATTER THAT PRODUCES NEW SUBSTANCES |
| CHEMICAL EQUATION | A SHORT, EASY WAY TO SHOW A CHEMICAL REACTION, USING SYMBOLS INSTEAD OF WORDS |
| CHEMICAL PROPERTY | A CHARACTERISTIC THAT IS OBSERVED WHEN A SUBSTANCE INTERACTS WITH ANOTHER SUBSTANCE |
| CHEMICAL SYMBOL | A ONE, TWO, OR THREE-LETTER ABBREVIATION OF THE NAME OF THE ELEMENT |
| COEFFICIENT | A NUMBER PLACED IN FRONT OF A CHEMICAL FORMULA IN AN EQUATION THAT INDICATES HOW MANY ATOMS OR MOLECULES OF EACH REACTANT AND PRODUCT ARE INVOLVED IN A REACTION |
| COMPOUND | A SUBSTANCE IN WHICH TWO OR MORE ELEMENTS ARE CHEMICALLY JOINED IN A SET RATIO |
| CONSERVATION OF MASS | THE PRINCIPLE STATING THAT MATTER IS NOT CREATED OR DESTROYED DURING A CHEMICAL REACTION |
| ELECTRON | A TINY, NEGATIVELY CHARGED, HIGH-ENERGY PARTICLE THAT MOVES IN THE SPACE AROUND THE NUCLEUS OF AN ATOM |
| ELEMENT | A SUBSTANCE COMPOSED OF A SINGLE KIND OF ATOM, THAT CANNOT BE BROKEN DOWN INTO OTHER SUBSTANCES BY CHEMICAL OR PHYSICAL MEANS |
| ENERGY | THE ABILITY TO DO WORK OR CAUSE CHANGE |
| MATTER | ANYTHING THAT HAS MASS AND OCCUPIES SPACE |
| MIXTURE | TWO OR MORE SUBSTANCES THAT ARE MIXED TOGETHER BUT NOT CHEMICALLY COMBINED |
| MOLECULE | TWO OR MORE ATOMS THAT ARE BONDED TOGETHER |
| NEUTRON | SMALL UNCHARGED PARTICLES IN THE NUCLEUS OF AN ATOM |
| NUCLEUS | THE CENTRAL CORE OF AN ATOM THAT CONTAINS THE PROTONS AND NEUTRONS |
| PHYSICAL CHANGE | A CHANGE THAT ALTERS THE FORM OR APPEARANCE OF A SUBSTANCE BUT DOES NOT MAKE THE MATERIAL INTO ANOTHER SUBSTANCE |
| PHYSICAL PROPERTY | A CHARACTERISTIC OF A SUBSTANCE THAT CAN BE OBSERVED WITHOUT CHANGING THE SUBSTANCE INTO SOMETHING ELSE |
| PRODUCT | A SUBSTANCE FORMED AS A RESULT OF A CHEMICAL REACTION |
| PROTONS | SMALL, POSITIVELY CHARGED PARTICLES IN THE NUCLEUS OF AN ATOM |
| REACTANT | A SUBSTANCE THAT ENTERS INTO A CHEMICAL REACTION |
| STATES | THE THREE FORMS (SOLID, LIQUID, AND GAS) IN WHICH MATTER EXISTS |
| SUBSCRIPT | NUMBERS IN A FORMULA THAT ARE WRITTEN SMALLER AND LOWER THAN THE LETTER SYMBOLS THAT SHOW THE NUMBER OF ATOMS OF AN ELEMENT IN A MOLECULE, OR THE RATIO OF ELEMENTS IN A COMPOUND |
