bonding Flashcards
what are the types of bonding
metallic
ionic
covalent
what does metallic include
two metals
what does metallic form
a giant lattice with delocalised electrons
why is metallic a good electricity conductor
the free electrons pass the current all the way through
what does ionic include
a metal and a non metal
what happens in a ionic bonding
metal gives away an electron
non metal accepts the electron
to get an empty / full outer shell
what does ionic form
a giant lattice of repeating links
what does ionic have high of
booking and melting points
can ionic bonds conduct electricity
only when molten
what does covalent include
two non metals
what does covalent do with electrons
they share it shown in dot and cross diagrams
what are positive ions called
cations
what are negative ions called
anions
what are alloys
a mixtures of metals with different sizes so the lattice is disrupted and can’t slide
stronger
what is an allotrope of carbon
structures made of the same elements but arranged differently
