Absolutely everything you need to know about the ATOM ... and much much MORE!
Hannah's ATOM UNIVERSE
Chemistry? more like che-MYSTERY? don't worry you have come to the right place!
1) ATOMIC STRUCTURE
- Brief history/ overview of the "Atom" + what is an ion?
- the nucleus, protons and neutrons (in addition to their FUNCTIONS)
- origin of the electrons- where are they located in the atom?
- Mass Spectrometer
- Use of nuclear symbol
- RAM and Isotope abundance non integer calculations from given data (mass spectra included)

Z
to find out the number of protons neutrons and electrons in atoms and ions
ELECTRON CONFIGURATION PART 1
- Emission Spectra, photons and excited electrons
- line emission spectra of HYDROGEN
Main energy levels of shells= 2n^2
-s p d and f sub levels and higher energies
- Sub levels and orbitals and probability of finding an electron
-Orbital defined energy state
-relationship between colour wavelength frequency and energy across the electromagnetic spectrum
- Distinction between a line and continuous spectrum
- Emission spectrum of the hydrogen atom + relationships between the lines and energy transitions to the 1st, 2nd and 3rd energy levels
- Recognition of the shape of an s atomic orbital and the px py and pz atomic orbitals
Application of Hund's rule, the Aufbau principle and the Pauli exclusion principle to write electron configurations up to Z = 36
HERE ARE SOME OF THE WONDERFUL THINGS YOU CAN LEARN!!!
KEY TERMS
ELECTRON CONFIGURATION PART 2
-In an emission spectrum, the limit of convergence at higher frequency corresponds to the first ionization energy
-Trends in first ionization energy across periods account for the existence of main energy levels and sub levels in atoms
- Successive ionization energy data for an element give information that shows relations to electron configurations
-Solving problems using E = hv
-Calculation of the value of the first ionization energy from spectral data which gives the wavelength or frequency of the convergence limit
- Deduction of the group of an element from its successive ionization energy data
-Explanation of the trends and discontinuities in first ionization energy across a period.
