Elements, Atoms, Molecules, Ions, Ionic and Molecular Compounds, Cations vs Anions, Chemistry

This chemistry video tutorial explains the difference between elements, atoms, molecules, and ions. It also explains how to distinguish ionic and molecular compounds also known as covalent compounds. Atoms are electrically neutral and contain equal number of protons and electrons. Ions have a net charge and contain a different number of protons and electrons. Positively charged ions are known as cations and negatively charged ions are known as anions. Atoms and Ions have the same number of neutrons. A molecule is particle consisting of multiple atoms. Pure elements are substances composed of one type of atom whereas a compound is made up of different types of atoms. Ionic compounds consist of metals and nonmetals and contain ions with charges. Covalent compounds or molecular compounds usually consist of nonmetals.

man i'm in chem 11. and now i know why teachers tell me to understand the basics. hey never too late to start something new. thank you for your help.

[jameschemistryaccount]

I love how calm this video is. It isn’t super heavily edited so it makes it very easy to watch and listen to. Thanks!

[frescamenzi]

u nailed it
chemistry is becoming more easier by looking your videos

[PratyushMehtaBtwo]

The Pitch and the rate which he delivers the information is absolutely appreciable.
😊😊☺️☺️
Thanks a lot,

[blastroisehunt]

Learning chemistry when I should be sleeping. 3 am current

[m.e]

This helped stopped my madness of confusion.

[puzzlehead]

I wished I discovered your videos earlier. Thank you for explaining the concepts clearly!

[AMAN_GAMER]

I wanna appreciate your work and would wanna say that you've made it so easy and manifest to have it resisted.

[chnazzzy]

my brain is just saying...."no.<3"

[julietmpereri]

You are more than my teacher thank you so much for your clear and perfect explanation

[jonahkane]

Extremely helpful video! I learned more from this video than I did from listening to my chemistry teacher for three months

[arbaaz]

I had doubt in molecule and compound and you cleared it so effortlessly

[JoelMogwasa]

This video is both educational and therapeutic — the voice is so calming yet the information is easily absorbable.

[TanayKesamReddy-qe]

man, these videos are such life savers, so easy and uncomplex to understand.

[namitagupta]

I'm in 9th ...and this was so helpful in understanding basic core concepts...thanks for this video

[shahadmerani]

one can never ace a subject or ever really understand if they’re clueless about basics, entered college 2 years after i graduated and i’m basically clueless so this is really helpful

[liltop]

Thank you so much. I knew everything in my chemistry class but I would fail questions determining the differences between Atoms, Molecules, Compounds and pure elements but thank you.🖤thank u so much
