Document Summary
Chapter 4: orbital review, orbitals ae described using quantum numbers, describe each quantum number, n: principal quantum number. This determines the spin of the electron; this gives opposite spins to an electron and allows two electrons to occupy an orbital. Paramagnetic: not all valence boxes/orbitals are filled: diamagnetic: all orbitals in the valence shell are filled, formation of ions, cations vs. anions, cations: ions that have a positive charge because of the loss of electrons. Ionization energy: energy required to completely remove the outermost electron from an isolated neutral atom in the gaseous state. Chapter 5: 5. 1 5. 8: types of representation for compounds, empirical formula: a type of chemical representation in which the compound is simplified to its lowest whole number ratio. This does not represent the actual numbers present in the compound. For example: c6h12o6 is simplified to ch2o: molecular formula: the actual chemical representation of a compound.
