Lattice Energy of Ionic Compounds, Basic Introduction, Charge vs Ionic Radius

This chemistry video tutorial provides a basic introduction into the lattice energy of ionic compounds. Lattice energy is the amount of energy released when 1 mole of gaseous ions combined to form a solid ionic compound. This video discusses the factors that affect the lattice energy of a compound. These factors are charge and ionic radius. The lattice energy of a compound is directly proportional to the charges of the ions and inversely related to ionic radii. This video explains how to use these two factors to determine which ionic compound has the most exothermic lattice energy values.

For all those wondering how to solve for lattice energy without specific values for ionic radii, recall that ionic radius increases to the left and downwards. You don't need a value to compare ionic radii - just its relative size. For instance, Na has a larger radius than Li.

[@uzairhussain4856]

Thanks alot. you explain well. your lectures helps me alot. keep it up.

[@alameen2496]

Thanks u too much
One among the best teachers I ever known

[@georgesadler7830]

Professor Organic Chemistry Tutor , thank you for a basic outline and introduction into Lattice Energy of Ionic Compounds in AP/General Chemistry. The two examples show the impact of Lattice Energy in different cases. In case one from the video, as the Charge increases, the Lattice Energy also increases. The second case also from the video, as the Radii decreases, the Lattice Energy increases. Pattern recognition also helps when learning this material. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.

I thought that a higher negative number like (-4) is smaller than (-1) so how can NaF be greater in LE than MgO?!?

[@elkh7414]

Thanks bro i like your video with my phone, with laptop. To express my respect.

[@timothymilsom1392]

Thanks so much! As always!

[@thebluebeyond2329]

This 🤔 concept becomes easy when you understand the periodic trends or the factors that influence the increase or decrease of the lattice energy.

[@zohasamdani]

But how would you know the size of the molecule just by looking at the PT?

[@Pete-da-peter]

I'm not sure whether or you read those comments or not. I can't tank you enough. I will definitely make a donation one day.

If you go to the description and see that under the topic listed, lattice energy has the same thumbnail as this video. I love that!

[@electricpants_abhay]

Thanks a lot man

[@shritikamallick123]

it is really useful

[@wickhere7996]

Thank you so much :)

[@DocileChupacabra]

Does the subscript of the element matter? Ex H2O vs H2O2, will the O2 affect the charge vs the O?

[@naodzerom4353]

so helpful

Thank you!

[@lailamnelson]

great vid

[@sobahlemaseko9189]

I'm not even sure if we covered this topic..the more I watch the videos the more I realize that I know nothing and this makes me more nervous because I'm writing an exam in one day's time.

Thanks Man

[@loisaddy686]

Thanks bro

[@jabbedcrab]

So when comparing sizes when the charge is the same, do you only compare the cations of one compound with the cations of the other? (Like Li and K?)

[@Alex-ty5xj]

You would go based on the amount of protons. More protons equals smaller lattice energy because the ion is bigger

[@k.v.saimadhav5016]

we cant take a phone to the exam.how will we know the size that elements ionic radius

[@edpen7717]

Thanks

[@ofeliaaaa]

Why you didn't show how to calculate lattice energy for kj/mol 😭

[@topthink9051]

Tnx so much

[@raniasafira5255]

thank you thank you thank you

[@rabiaakbar283]

what if there is an ionic compound such as C02? Would it be larger than Al2O3?

[@J1hn1]

To determine which compound that has the highest lattice energy, the definition says it has to be an ionic compound. CO2 ( C + O2 ) are to close in electronegativities so a covalent bond is form.

[@kingsleyeshun_]

Awesome

[@ndrinalimani2203]

and i didn't get how, if we increase the charge LE increases, and also if we increase the radius the LE decreases, but in the case of anions, while increasing the charge, the radius increases, does this mean that lattice energy is bigger (bigger charge), or its smaller (bigger radius)....?

[@user-ks5ci6bs6x]

dumb dumb dont study chemistry

[@samchy6924]

thanks

[@mrmakertamil2439]

😮😮😮😮🎉🎉🎉🎉 thanks bro❤

[@tonywang6063]

which one would have a higher LE, large ions or large radius

[@JoseOrtiz-ij8te]

Tony Wang large ions

[@BryceKing01]

How do you determine ionic radius and the pecal meters? Thanks for a helpful video!

[@backtogod7495]

Ionic radius is already determined for each atom, you just have to learn them
Anyways in this question the exact ionic radius isn't needed. Just make sure which atom is larger and which is smaller.😊

[@backtogod7495]

Picometer*

[@williammcfarland420]

at 1:20 he mixed up distance between the ions and atomic radius, which are inversely proportional.

[@arikaazka4443]

How would we know the charge

[@NewWesternFront]

something a little annoying to grasp at first is that they are always asking for the energy higher in **magnitude**. I was confused at first because it felt like the answer to highest lattice energy would involve the least negative number. My book and homework doesn't always reference absolute value or magnitude so it seems a little unintuitive at first. I mean in general it seems unintuitive why there is a release of energy during the solid ionic formation but i guess sometimes in these classes you just have to keep plodding along

[@anonymouslymj1064]

What about comparing ionic compounds with multiple anions or cations?

[@backtogod7495]

It's the same,
You take their product.

[@michellec.4291]

How do you get those values in pm?

[@muhamedamin9600]

look at the periodic table

[@danielnunez3206]

what is K in this formula?

Ur a god

[@milliedoyle3093]

Surely you mean 'more exothermic' as opposed to 'higher'? Because 'higher' indicates a larger number ie more endothermic. It's quite confusing when you use the terms incorrectly.

[@fluffy_creature2613]

How do i know the charges of each element

How come Na is a gas?

[@Ghosttt3]

When looking for lattice energy, both ions will always be in gaseous state forming into a solid

[@rukukaru2450]

I came here because the uni I'm applying to have this in this exam, but when I ask, it's for year two :'D

[@mattkessel36]

My book didn't even imply that charge or atomic radius were factors of lattice energy. Thanks!

[@siddhavinayakacharya5409]

i ahev doubt that whether energy relase or absorb

[@hunzalashahid4000]

energy is released as the reactions are exothermic

[@MrTrex183]

How did you calculate the lattice energy and ionic radii?? smh

[@elias-hq6ft]

Ionic radius increases to the left and downwards of the periodic table. You can use relative sizes as opposed to actual values to solve for which of the compounds has a higher lattice energy.

[@christinaf.51]

But what if pm isnt given?

[@Pal0maSama]

Well, the order of size for atoms and ions goes anion(negative ion), the neutral atom, and the cation (the positive ion). The greater the positive charge the smaller the ion. However, the greater the negative charge the smaller the ion. Anions are typically bigger than cations.

[@Pal0maSama]

The comment above should say "the bigger the ion" for the anion.

[@scottdylanwoolf]

you have the atomic radii memorized??

[@alejandromoyron8297]

I thought he was looking them up but he wasn't. I'm impressed

[@vladabalinsky7276]

if you look at the periodic table, the atomic radii decrease going from left to right, and from bottom to top. keeping that in mind, you can imagine in your head which has the bigger lattice energy just by thinking of their sizes. but yeah its easier to do so by counting charges. (just after typing this i saw you wrote your comment a year ago but i already typed this outttt. sorry)
