ionic bonding 3.3 Flashcards
why do metal atoms get a full outer-shell
positively charged and more stable
what is the loss of electrons called
oxidation
how do metal atoms form metal ions
lose their outer-shell electrons to gain a full outer-shell
how do non-metal atoms form non-metal ions
gain electrons to fill their outer-shell
why do non-metal atoms get a full outer-shell
become negatively charged, more stable
what is the gain of electrons
reduction
what happens when metals and non-metals react
the metal atoms give electrons to the non-metal atoms, all atoms form an ion with a full outer shell
in ionic compounds, the charges balance
postive=negative
how are ions arranged in an ionic compound
giant ionic lattice
what is ionic bonding
electrostatic attraction between oppositely charged ions
what type of attraction is ionic bonding
very strong attraction
why do ionic compounds have high melting points
ionic bonds are very strong
lots of bonds in giant ionic lattice
breaking the bonds requires lots of energy
can solid ionic compounds conduct electricity
no, ions can’t move freely
can liquid or aqueous ionic compounds conduct electricity
yes, ions can move freely
