| Question | Answer |
|---|---|
| Niels Bohr | 1915 Proposed a planetary model of the atom to explain bright light spectra. |
| Bright Light Spectrum | Wavelengths of light released when electricity is passed through a sample of an element. |
| characteristic of bright light spectrums | Each element has a unique spectrum. Elements can be identified by their characteristic bright line spectrum. |
| bohrs model | bohr suggested the electrons occupy specific orbits in stable cofiguartion |
| bohrs model | Electrons are lazy! – They will occupy the lowest available energy level. Ground State When electrons gain energy they “jump” up to higher levels. o Excited State |
| Erwin Schrondinger | Created an equation to explain this. But in order to solve this he needed to look at electrons as both waves and particles! |
| created | This lead to the invention of the wave-mechanical model of an atom and This was the birth of quantum theory |
| new model | Electrons are found in orbitals! Not Orbits |
| orbitals | 3 dimensional region where Electrons are most likely to be found o We can never know for sure |
| how do we describe an electrons position | But we can describe an electrons position using quantum numbers! o An electrons address! |
| 4 quantum numbers | prinicipil, orbitol, magnetic, spin |
| when doing quantum numbers | energy must fill lowere leveels fir or levels closer to the nucleus use periodic table |
| the magnetic quantum number | s shell – one orbital – 2 electrons p shell- 3 orbitals – 6 electrons (2x, 2y, 2z) d shell- 5 orbitals – 10 electrons F shell- 7 orbitals- ? electrons |
