Ionic Bonding Flashcards
whats a positively charged ion called
cation
whats a negatively charged ion called
anions
what keeps the cations and anions in place in an ionic lattice
electrostatic attraction between the anions and cations
whats the electrostatic attraction between anions and cations called
ionic bonding
what charge does aluminium cation have
3+
charge of zinc cation
2+
charge of iron cation
2+ / 3+
charge of copper cation
1+ / 2+
charge of lead cation
2+ / 4+
which groups dont form ionic bonds
group 4 and 0
whats the suffix for anions
ide
whats a compound ion / polyatomic ion
a compound made up of diff ions
whats the ionic formula for carbonate ions
CO32-
ionic formula for sulfate ion
SO42-
ionic formula for ammonium ion
NH4+
ionic formula for hydroxide ion
OH-
ionic formula for nitrate ion
NO3-
ionic formula for manganate ion
MnO4-
ionic formula for phosphate ion
PO43-
ionic formula for hydrogen carbonate ion
HCO3-
format of naming ionic compounds
cation followed by anion
formula for sodium chloride (salt)
NaCl
whats the overall charge of ionic compounds
neutral
if an ionic compound has stronger ionic bonding then it will require …. energy to break
more
when a liquid ionic compound is boiled, it turns into gas and all ionic bonds are
broken
describe electric conductivity in solid ionic compounds
no conductivity
describe condctivty in liquid
yes
can ionic compound gases conduct electricity
no
why do ionic compounds have high mpt high bpt
strong attraction between cations and anions
what factors affect the force of attraction between two oppositely charged particles
the distance between particles
the charges of particles
larger charges means
stronger electrostatic attraction
larger distance / larger ions means
weaker ionic bonding
how do you know if an atom is larger than another
theres a larger distance between the nucleus and outer shell electrons
as you go down group 1, the size of ions
increases
what are isoelectronic ions
ions with the same number of electrons
for isoelectronic electrons, which ones are the smallest
ones with the greatest nuclear charge
describe solubility of ionic compounds in water
soluble
why are ionic compounds brittle
if the compound is moved, the ionic lattice structure changes and the repelling ions come over each other, forcing the compound to break apart
in which states do ionic compounds conduct electricity
liquid and in aqueous solution
