ionic bonding 3.3 Flashcards
what’s the loss of electrons called?
oxidation
what is ionic formation?
making the outer shell of electrons full and more stable
what’s the gain of electrons called?
reduction
what’s forming ionic compounds?
when metals and non metals react and the metal atoms give electrons to the nonmetal atoms to form an ion with a stable full outer shell
what diagrams do you use for ionic compounds?
dot cross diagrams
what happens in any ionic compound?
charges balance
positive = negative
for example
Li+ and S2-
are put together
Li2S
what’s the ionic structure?
giant ionic lattice
ions alternate
what is the definition for ionic bonding?
ionic bonding is the electrostatic attraction between oppositely charge ions
what attraction is ionic bonding?
very strong attraction
why is the melting point for ionic compounds very high?
- ionic bonds are very strong
- a giant ionic lattice has lots of ionic bonds
- breaking ionic bonds requires lots of energy
what circumstances can ionic compounds conduct electricity?
liquids and aqueous
- high conductivity
- ions can move freely
what circumstances can ionic compounds not conduct electricity?
solids
- no conductivity
- ions can’t move freely
what charge does Li, Na, K have?
+
what charge does Mg, Ca, Ba have?
2+
what charge does Al have?
3+
