Document Summary

Every level has one s : s orbitals can hold a maximum of 2 electrons, designation- 1 (energy level)s(orbital type) (number of electrons, the s orbitals will have spin up or spin down . If you have 1 electron hydrogen atom it is naturally going to go into 1s but if you put in some energy it can equally get into any level: nuclear charge shielding in multi-electron atom. He guessed at the properties at the three elements that were missing and was actually correct on he guessing: based on these gaps, mendeleev was able to predict the occurrence of three new, as yet undiscovered elements. He went so far as to predict physical properties of these elements: subsequently, all three of these elements were found-gallium, Chapter 6: magnetic properties of atoms, any time you have moving charge that makes a magnetic. If all electrons are paired, the spin magnetic moments all cancel and the atom is called diamagnetic.
