| First rule in John Dalton's Atomic Theory. |
|
Definition
| All matter is composed of extremely small particles called atoms. |
|
|
Term
| Second rule in John Dalton's Atomic Theory. |
|
Definition
| Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties. |
|
|
Term
| Third rule in John Dalton's Atomic Theory. |
|
Definition
| Atoms cannot be subdivided, created, or destroyed. |
|
|
Term
| Fourth rule in John Dalton's Atomic Theory. |
|
Definition
| Atoms of different elements combine in simple whole-number ratios to form chemical compounds. |
|
|
Term
| Fifth rule of John Dalton's Atomic Theory. |
|
Definition
| In chemical reactions, atoms are combined, separated, or rearranged. |
|
|
Term
| Law of multiple proportions. |
|
Definition
| If two or more different compounds are composed of the same two elements, then the ratio of the masses of the second element combined with a certain mass of the first element is always a ratio of small whole numbers. Ex. 2.66g O combined with 1.0g C and 1.33g O combined with 1.0g C. The ratio of the masses of O in these two compounds is 2.66 to 1.33 which equals 2 which is a whole number. |
|
|
Term
| Law of definite proportions. |
|
Definition
| A chemical compound contains the same elements in exactly the same proportions by mass regardless of the size of the sample or source of the compound. |
|
|
Term

|
|
Term
| J.J. Thomson's contribution to atomic theory. |
|
Definition
| Worked with the cathode ray tube and identified that the atoms contained electrons. |
|
|
Term
| Rutherford's contribution to Atomic Theory. |
|
Definition
| Worked with the gold foil experiment in order to identify that the atom had a nucleus. |
|
|
Term
| Joseph Louis Proust's contribution to the Atomic Theory. |
|
Definition

|
|
Term
| Antoine Lavoisier's contribution to Atomic Theory. |

|
Term
| Relative mass and charge of a proton. |
|
Definition
Relative mass: 1
Relative charge: +1 |
|
|
Term
| Relative mass and charge of a neutron. |
|
Definition
Relative mass: 1
Relative charge: 0 |
|
|
Term
| Relative mass and charge of an electron. |
|
Definition
Relative mass: 1/1836
Relative charge: -1 |
|
|
Term
| Structure of an atom including location of proton, electron, and neutron with respect to the nucleus. |
|
Definition
| The nucleus is at the center of the atom and contains protons and neutrons. Surrounding the nucleus is a region containing electrons. This region is very large compared to the size of the nucleus. |
|
|
Term
|
Definition
| A unit of mass that is exactly 1/12 the mass of a carbon-12 atom. |
|
|
Term
| State how isotopes of an atom differ. |
|
Definition
| They all have the same number of protons, but the number of the neutrons varies between isotopes. |
|
|
Term
| Use the concept of isotopes to explain why the atomic masses of elements are not whole numbers. |
|
Definition
| Isotopes occur for each element and consist of different numbers of neutrons. The atomic mass is an average of the combined protons + neutrons for the isotopes. |
|
|
Term
| Calculate the average atomic mass of an element from isotope data. Element Y has two isotopes. One has a mass number of 10, and has a relative abundance of 20%. The other isotope has a mass number of 11 and a relative abundance of 80%. |
|
Definition
| (10X20%) + (11X80%) all divided by 100 = 10.8 |
