Term
the significance of de Broglie's hypothesis is this:
its like how many platforms there are. ex: how many orbitals are possible in 6p? 3!
, as z increases, the attraction between the nucleus and any given electron increases.
the increased attraction lowers the energy of the orbital and causes the orbital to
contract
a complete description of the behavior of an electron in an atom must
incorporate wave-particle duality
