The currently accepted model of an atom where the exact location of electrons is unkown? a. electron cloud, quantum, or orbital model b. bohr model c. quark model d. plum pudding model

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
