ATOMIC STRUCTURE AND PERIODICITY
• Why do some ionic compounds precipitate and others don
• Why do some compounds easily lose H+ and others gain it
• Why do some elements gain electrons and others lose som
• Why do elements want to obtain the same number of elec
as nearby noble gases?
Chemistry is pretty much all about how electrons are located around the nuclei and
how they dance in between these.
Let’s find out about the way electrons spread themselves around the nucleu
