Diameter of a nucleus
10^-15m
Diameter of an atom
10^-10m
How to calculate atomic mass
(isotope mass * % + …) / 100% = ___ amu
What is a photon
Light released and perceived when an electron goes back to it’s natural state
What happens when an atom is excited
Electron move to higher orbitals (not between) and back to original state
Explain the steps leading to spectroscopy
- Electrons excited
- move to higher orbitals
- Excess energy released as light (photons) when electrons move back
4.We see the emission spectrum
Whose model theory does this support
Bohr model
What is Schrödinger’s model based on
The probability of an electron being in that zone
