Type I Binary Ionic Compounds - Naming and Writing Formulas

[@jakevoinar-fowler8409]

Thank you! man you just made me understand more in 10minutes than my chem teacher can in two weeks

[@Nate-qu9gt]

Same

[@the_bro.09]

of course the same

[@SohYeopLee]

I've been searching thru Khan academy and other lecture sites but this is by far the best 10 min lecture!! Thank you so much

[@ChemAcademy]

You are most welcome

[@VapeVader]

why isn't the 3 after Na for sodium phosphide

[@ChemAcademy]

+Alex Archibeque my mistake...it should be Na3P...you are correct

[@VapeVader]

+Chem Academy sweet thanks. Good vids by the way

[@merky4382]

This helped me understand why the "Crisscross" method works, thank you.

[@ibisdope]

you just taught me more than my chem teacher- here 👑 i think u dropped this

[@nandagutierrez9104]

Thank you!! you explained better than my college teacher. Makes more sense to me now

[@explodingzack4937]

you are in college doing this?

[@Tbryant22]

Hi can I ask is Sodium Chloride correct? Why is the 3 in the phosphate.? I think it should be in sodium since sodium has a charge of +1 so if we add it to three phosphide 3- we can have Na3P 😅😅 sorry Im just confused

[@yesiusethisapp]

typo i believe

[@arianannienunal4999]

Yes, i found this helpful. Thank you!^^

[@jezzales]

thank you so much, this video was a BIG help :)

[@etherealeagle7680]

Sodium Phosphide. Sodium has a + charge. Phosphorus 3- charge. Shouldn't the three subscript be next to the sodium to balance things out?

[@steveng3770]

Yeah I think so, because if you look further down the examples at Sodium Sulfide it’s written the other way Na2S

[@betty0457]

Why doesn’t the chem book just say that? 😭 so much easier to understand thank you!

[@brooks1520]

Slow down on the regular chemistry students. You're a soul crusher...

[@Larry-bm7ez]

The criss cross method will save you guys so much time on this!

[@JustAPersonWhoComments]

i got this video for doing the assignemt, now im learning it lol

[@jonathanherrera9015]

Thank you very much!!!

[@alexandramocalis6778]

wow you rock thank you!!!!!!!

[@mckennasuorsa6455]

how do u know the subscript if it's a transition metal?

[@mightyrupert344]

Look look, it’s okay if you don’t know. Sometimes you just got to take an f letter grade for a test while looking mighty and cool, and once you get home, cry...

thank you

[@aliciamartinez3796]

Thank you!!

[@sassyrasta3053]

How is Ag, Zn, Al considered to be group 1 or 2 ?

[@mos5839]

I'm confused about the "and " I think he meant "or" ? I hope

[@shyshyshy22]

Can you please explain how to do Potassium iodide? I see that it should be KI, but i keep getting K5I when i solve it...

[@danielbrannon1520]

They both have a charge of one +/- so they cancel eachtoher out so you just get KI

[@carolinecohen997]

how can silver be in this at all? its not a metal or a non right?

[@Akaeru]

Pretty sure it's a metal lol, you probably confused it with aluminum

[@inno10012]

Why the 2 at CsF (Caesium Fluoride)?

[@ChemAcademy]

+Innocent Ng. BANZI My mistake it should be CsF

[@miaesworthy2464]

there is an error on the try on your own- sodium phosphide = Na3P NOT NaP3
