ionic bonding Flashcards
why are group 0 atoms unlikley to bond ?
they are noble gases and have full outer shells so are very unreactive and have no need to bond
why do atoms bond ?
to have a more stable electron arrangement.
what is ionic bond between ?
metals and none metals
where are the electrons transferred in ionic bond ?
from metal to non metal atoms
what is formed from ionic bonds ?
positive and negative ions
how do you shown ionic bonding ?
dot and cross diagram
what type of ion is something that has gained an electron
negative ion
what type of ion is something that has lost an electron
positive ion
what are atoms in ionic held together by ?
electrostatic forces
ionic bonding the result of …..
electrostatic forces between opposite charges ions
what structure are ionic compounds always in ?
lattice
explain the melting point ionic compounds ?
high melting points caused by giant structure .Lots of energy is needed to break up the lattice of ions
can ionic compounds conduct electricity ? explain your answer ?
when molten or dissolved in an aqueous solution but not when solid .this is because the ions that carry the current are free to move in a liquid state but not as a solid
are ionic compounds brittle ?explain
yes . the ions may move when receiving a blow and cause them to interact with like ions
