|---|---|---|---|
| 1 | Neils Bohr | Early 1900s - Denmark | Science Quiz on atoms - Dates |
| 2 | Neils Bohr | 1910- Electrons orbit the nucleus at specific distances. "Electrons gian energy when they move closer to the nucleus and loose energy when they move further away" (wrong) Came up with bohrs model (planetary model) of the atom. Problems- only works with one electron,how can you not move inbetween energy levels | Atomic Theory |
| 3 | neils bohr | atom is mostly empty space, positively charged massive nucleous, negatively charged electrons, eloectrons have fixed orbits (fixed energy levels), electrons can become "excited" and move to higher energy levels for brief periods of time or electrons can move down to lower energy levels and emit light. | atom models...might be wrong... |
| 4 | Neils Bohr | proposed that an electron is found only in specific circular paths or orbits around the nucleus | Chapter 5 |
| 5 | Neils Bohr | 1913 removed electrons from atom with different amounts of energy and reasoned that atoms orbit nucleus at different distances from nucleus. Created Solar System Model | Chemistry |
| 6 | Neils Bohr | graudate student, electron shells, atomic number | Mid-Term Definitions |
| 7 | neils bohr | planetary model: electrons move in fixed paths aroun nucleus, have fixed energy | chem hons s1! |
| 8 | Neils Bohr | discovered the electron shells | famous scientists |
| 9 | Neils Bohr | Worked in 1913 | Scientists |
| 10 | Neils Bohr | Created planetary (Bohr) model of the atom | Scientists |
| 11 | Neils Bohr | Said that electrons move in specific circular orbits around the nucleus, based on their energy levels. | Scientists |
| 12 | Neils Bohr | electrons occupy energy levels in the atom | Atomic Theory |
| 13 | neils bohr | modern atomic model | SCIENCE |
| 14 | neils bohr | modern atomic model | SCIENCE |
| 15 | Neils Bohr | Danish physicist whose atomic model laid the foundation for quantum theory (1913) | RHS Chemistry Set 5 |
| 16 | neils bohr | planetary model of the atom; specific paths in which electrons move | Chem unit 2- Atomic Model |
| 17 | Neils Bohr | electrons orbit the nucleus like planets orbit the sun | Sam People for Matter Test |
| 18 | Neils Bohr | In 1913, he introduced a model of the atom named after himself. In this, electrons wre set in whole number (called "quantum") orbits around the nucleus. | Atom Scientists |
| 19 | Neils Bohr | the scientist that proposed that electrons in an atom are found in energy levels as they orbit the nucleas of an atom | Science Test Unit 14 11.10.08 |
| 20 | Neils Bohr | invented cathode | Chemistry Theories |
