WebThe subsequent ions are more stable than the previous ones i.e. [Cu(NH 3) 2 (H 2 O) 4] 2+ is more stable than [Cu(NH 3)(H 2 O) 5] 2+ and so on. But you'll notice that the stability constants are smaller for each subsequent ion. This is typical when studying individual equilibrium constants in a reaction. Webc) 7 and 1. d) 8 and 8. b) 1 and 7. The "octet rule" relates to the number eight because: a) only atoms with eight valence electrons undergo chemical reaction. b) ions with charges of +8 and -8 are very stable. c) atoms, during compound formation, frequently obtain eight valence electrons. d) all electron subshells can hold eight electrons.
