### Isoelectronic & Isotones * Isoelectronic: Same number of electrons * Isotones: Same number of neutrons ### Atomic mass * Mass of one atom = (Mass number) amu * Mass of one atom = (Mass number) x 1.67 x 10^-27 kg * Or mass number x 1.6 x 10^-24 g where 1 amu = 1.67 x10^-27kg or 1.6...
### Isoelectronic & Isotones * Isoelectronic: Same number of electrons * Isotones: Same number of neutrons ### Atomic mass * Mass of one atom = (Mass number) amu * Mass of one atom = (Mass number) x 1.67 x 10^-27 kg * Or mass number x 1.6 x 10^-24 g where 1 amu = 1.67 x10^-27kg or 1.6 x 10^-24 g * How to find the mass number of an atom? * Add the mass number of protons and neutrons. ### Molecular mass * Sum of the masses of all the atoms. * For example, CO2 = 12 + 16 x 3 = 60. * M.N = 60 x 1.67 x 10^-27 kg = ……….. ### Mole Concept (Gram Concept) * 1 Mole = 6.0224023 x 10 ^23 = 6 x 10 ^23 NA * (NA x amu/gram) = 1 * Molar mass = 8
