Atomic structure
atomic number —> no. of proton
nucleon (mass) number —> no. of proton + neutron
nuclide notation —> (nucleon) mass number / no. of proton (e.g 7 / 3 Li)
electronic configuration (e.g 2, 8, 8)
relative mass (protons = 1, neutron = 1, electron = negligible)
relative charge (protons = +1, neutrons = 0, electrons = -1)
Beryllium loses 2 electrons to form an ion with a charge of 2+ —> Be^2+ has a stable duplet configuration
Fluorine 2.7 gain 1e^- —> 2.8 F^- Fluoride ———> stable octet configuration
isotope —> equal numbers of protons but different numbers of neutrons, similar chemical properties because same number of valence shells and electrons
7 Li (95.15%) 6 Li (4.85%) —> 95.15/100 x 7 + 4.85/100 x 6 = 6.9515
