ionic compounds Flashcards
(6 cards)
what is ionic bonding
strong electrostatic force of attraction between metal and non-metal ion
metal - looses electrons (+charge)
non-metal- gains electrons (- charge)
Describe what happens when sodium reacts with fluorine to produce sodium flurried
-sodium looses an electron to make a positive ion
-fluorine gains am electron to make a negative ion
-they both have full outer shells now
-forming an ionic bond
explain why ammonia has a low boiling point
-simple molecular structure
-has weak intermolecular forces
-that require large amounts of energy to be broken and they
-have strong bonds
how are ionic compounds held together
-by strong electrostatic forces that act in all directions between oppositely charged ions
state properties of ionic substances
-high melting/boiling points
–don’t conduct electricity when solid
-do conduct electricity when molten or in solution
explain why ionic substances don’t conduct electricity in solid but do in solution/molten
-in solid ions cant move
-in molten/solution ions move around and carry their charge
