Ionic Bonding Flashcards
Ionic charge affects ionic bonding
Greater charge on an ion means stronger ionic bond is and therefore higher melting/boiling point
Ionic radii affects ionic bonding
Smaller ions pack closer together than larger ions
Electrostatic attraction gets weaker with distance so small closely lacked ions have stronger ionic bonding.
Therefore ionic compounds with small closely packed ions have higher melting and boiling points than ionic compounds made of large ions
Isoelectronic ions ionic radius decreases as atomic number increases
Isoelectronic ions are ions of different atoms with same number of electrons
As the number of electrons stay the same the number of protons increases.
Meaning that the electrons attracted to the nucleus more strongly, pulling them in closer so ionic radii decreases
