Chemistry
Knowing the bonds
| Term | Definition |
|---|---|
| Compound | When 1 or more atoms are bonded together |
| Molecule | A compound that has covalent bonds |
| Formula Unit | A compound that has ionic bonds |
| Ionic Bonds | -There is a transfer of electrons -Metal + Nonmetal (ex: NaCl) |
| Covalent Bonds | -Atoms share electrons -Two NONmetals (H20) |
| Chemical Formula | Notation using symbols and numbers to represent the composition of a substance. |
| Molecular Formula | Shows the number and kinds of atoms actually present |
| Empirical Formula | Gives the simplest ratio between atoms. |
| Coefficients | Used to show the presence of multiple compounds |
| Formula Unit | Ionic, always REDUCE to empirical ex: Na2Cl2 --> NaCl |
| Diatomic Molecules | elements that always exist as a molecule (the magic 7) |
| Size/Radius | Atomic radius increases as you move from right to left through a period. -Nuclear charge increases which draws in the outer electrons |
| Shielding | inner electrons block the nuclear charge toward the outer shell electrons. |
| Electronegativity | The atoms's ability to pull an electron towards itself when bonded. |
| Ionization Energy | The amount of energy required to pull an electron off. |
| Mono | 1 |
| Di | 2 |
| Tri | 3 |
| Tetra | 4 |
| Penta | 5 |
| Hexa | 6 |
| Hepta | 7 |
| Octa | 8 |
| Nona | 9 |
| Deca | 10 |
