Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K⁺ and Cl⁻ ions, is named potassium chloride.

I am at the 8th grade

I'm just watching these on my own. This is wonderful stuff.
Oh god, you've saved my life
I have a basic understanding of chemistry so I get most of what you're saying, but I've been watching the videos in order and you keep referring to stuff you haven't mentioned yet. Like 'outer shell' and groups in the period table.
And you refer to potassium chloride as an ionic compound.
Matthew Collins because at this point you should know the basic concepts leading up to this video. Are you going to go straight to calculus if you don’t know algebra? 🧐
@@lather7785 he talks about it in his other videos.
@@ranal2075 can you tell me in what order should i watch chem videos 😢having the same problem
are u sure u have basic understanding my dude? I've been learning Chem from start for about 1 month and I know that, I knew completely nothing before
Omg u saved my life
Omg 160 k people watched the vid and there is only 2 comments
Thanks for the help.
Still dont understand huhu..... What was the +1 and -1 for.. please answer me😧
that's the charge of the element. basically in a periodic table group 1 elements have a positive 1 charge, group 2 have +2, group 13 have +3, group 14 can have either positive or negative 4, group 14 have negative 33, grp 15 negative 2, grp 16 negative 1, and group 18 is 0
That is what makes it an ion! When the element has a charge, either positive or negative, it becomes an ion. Now to know the charge for an ion, it's easier to imagine the periodic table as round and in a cycle going from 1+ to 3- and then 1-. I hope this helps.
If someone still doesn't understand after reading both of the above answers, i suggest you to learn about atoms, its properties, about how atom need to stabilize its electrons, then you will understand about ions and charges... Then you need to know about groups and period in periodic table and what that has to do with its charges...
🟥 *_Summarised by GPT-4_*
(1) *Ions* : Atoms can lose or gain electrons to achieve a more stable electron configuration.
When they do this, they become charged particles called ions.
- *Cations* : Atoms that lose electrons become positively charged and are called cations.
- *Anions* : Atoms that gain electrons become negatively charged and are called anions.
(2) *Formation of Ionic Compounds* : Ions with opposite charges are attracted to each other. They come together to form neutral compounds known as ionic compounds.
(3) *Naming Ionic Compounds* : The naming convention for ionic compounds involves writing the name of the cation (positive ion) first, followed by the name of the anion (negative ion). For instance:
- *Potassium (K)* : An element from the alkali metals group (group one of the periodic table) tends to lose one electron and become a cation. When ionised, it's referred to as a "potassium ion" or "potassium cation".
- *Chlorine (Cl)* : An element from the halides group tends to gain one electron and become an anion. When ionised, instead of being called "chlorine anion", it's named "chloride".
- *Potassium Chloride (KCl)* : When potassium (a cation) and chloride (an anion) come together, they form an ionic compound named "potassium chloride".
Gotta watch this..
Hi why the Cl has -1 charge please explaine?
because the ion is negatively charged. an ion becomes negatively charged when it has more electrons then protons, in this case since it has written -1 it means that it has 1 more electron then proton
Why you wrote the name in lowercase? Is it included to naming?
Thank you
saved my life
where is the next video that goes with this
why is it only chlorine that gets called "chloride" and not potassium?

*then you look at me* Well, I'm less confused than before. *raises fists to face level and shakes them* THANK YOU KHAAAAAAAAAAAAAAAAAAAAAN!!!

cool
oh wow
wow
joey diaz
h
It’s too hard to watch videos like this especially related to education huh
oh wow
