(1) False - The statement is referring to Hund's rule, which is only true for atoms in their ground state. However, if an atom is in an excited state, some orbitals may have more than one electron before all orbitals have one electron. 
(2) True - The nucleus of an atom is always positively charged, as it contains positively charged protons.
(3) False - Neutrons are actually slightly more massive than both electrons and protons.
