WHAT IS QUANTUM MECHANICS

The term 'quantum' comes from the latin root 'quantus' meaning 'how many', and implies a numerical quantity that can be counted and quantified. 'Mechanics' is what we call the field of physics that studies motion. Therefore, the field of quauntum mechanics investigates 'countable motion'. Like all fields of science, quantum mechanics was developed in order to explain an observed behaviour of the world that cannot be explained by existing scientific fields and models.

QUANTUM MECHANICAL QUESTIONS IN CHEMISTRY

1. Why do atoms emit discrete, countable frequencies of light?
2. Why do electrons exist as strange shapes called orbitals?
3. Why do negatively charged electrons not get sucked into the positvely charged nucleus of an atom?
