Question | Answer |
Hund? | Electrons must fill orbitals singly before they pair. |
Mendeleev? | Arranged the elements in his periodic table in order of increasing ATOMIC MASS. |
Aufbau? | Electrons occupy the orbitals of lowest energy first. |
Thompson? | BUilt the plump-pudding model. Electrons should be spaced out in a positive charged place. |
Rutherford? | discovered the nuclues. |
Dalton? | Discovered the 1st scientific atomic theory. |
