ionic bonding (3.3) Flashcards
what is a loss of electrons called
oxidation
what is a gain of electrons called
reduction
when electrons are lost, does the atom become negatively or positively charged
positively
what tends to happen when forming non metal ions
non metal atoms tend to gain electrons to fill their outer shell
when electrons are gained, does the atom become negatively or positively charged
negatively
what happens when metals and non metals react
the metal atoms give the non metal atoms electrons
what do dot and cross diagrams show
ionic bonding
what are ionic compounds arranged into
giant ionic lattices
what is the definition for ionic bonding
the electrostatic attraction between oppositely charged ions
what is ionic bonding always?
a very strong attraction
why do ionic compounds have high melting points?
ionic bonds are very strong
in a giant ionic lattice there are lots of ionic bonds
breaking all the ionic bonds requires a lot of energy
why do some ionic compounds have higher melting points?
their ions have higher charges which makes the ions even stronger and harder to break
what does electrical conductivity require in ionic compounds?
charged particles that can move freely
can a solid ionic compound conduct electricity?
no
