Chemistry: Introduction to isotopes and atomic structure

[MrCHAUDRYALI]

Can any one tell me about the radio activity ?

[kevkongable]

Well explained thanks

[Zayin1993]

Interesting stache!

[joshtong1234]

Guys the correct way to get the Neutron is

Atomic mass subtracted by the numbers of Protons. Have a Good day!

thumbs up so everyone will see

[meganoble1]

thank you!!!!

[SolomonsTime]

pretty good...

[SolomonsTime]

[CanYouFindNemo]

This has helped me sooo much

[bakedbeansification]

confusing go away.

[Chalron]

Thanks for this video - it has helped me to understand with the diagrams.

1:47 we get nitrogen :D

"The nucleus is in fact not stable, we'll have lots more to say about that later."

I can't wait!

Quality moustache though.

Joking aside i kinda lost the plot when i stepped up to Higher Level Chemistry and Physics at school (don't know what the equivalent qualification would be in America, you do it over here in Scotland when your about 17, assuming you pass the O/Standard Grade).

[tartarcreamxx]

i hate isotopes!! most confusing part of physics!

[Superspy4596]

I want to bone you so hard!!!!

[ImaBigCullenist]

itz actually physics not chemistry

[Lloydy9101]

nice ! TY

[DCHurlford1]

Isotopes are atoms of the same element which have the same atomic number but a different mass number due to a different number of neutrons in the nucleus.

About the only thing i remember from 'O' Grade Chemistry at school, ha ha.

[zoneyzoo]

In the elemental table Carbon's atomic number '6' is placed on top of the symbol C and the atomic mass (proton & neutrons together) are placed below the the C.

So why in this illustration of of different carbon atoms do we have the reverse of the atomic number and the atomic mass?

Thank you so much for this video it has helped me to understand this concept better.

[MisterTullaci]

i have 5g of isotope187 made in ucraina , how can i use it

[iSachin1996]

how did u make a video commentary at the top left

[fs32464]

what is the istopes, and how does get into the atom. Is something that is added to the nuclus. If yes how does that happen, if not so what the hell is it.

[enienileg]

too much hand motion. but helpful

[Hansnf]

How do you mesure how much isotope is it in a sample?

[pithikoulis]

The bigger the difference between the number of neutrons and protons, the more unstable the atom is. Is that right?

[MrIvan72]

do you learn this in highschool?

[mcraregreat234543]

they need to make a proton canon this could potentially turn lead into gold.

[IQ20000Berta]

very simple but helpful lol

Du verflixtes Täschchen ich will dich und ich werde dich bald unter meiner Obhut haben.

That's for sure

[IQ20000Berta]

@IQ20000Berta Schade hat eben nicht sein wollen. Dafür ist an die rätselhafte Zeit geschnurrt worden  watch?v=AIWOtiONPJY

[IQ20000Berta]

@IQ20000Berta BerndAustria i want to kill you, perhaps it will happen hehe

[iphonet33n]

Helped my on my project

[PathofReason]

The part that I don't understand is where does this neutron come from? how does it even get there in the first place?

[Mindbitesdotcom]

Many elements have several different isotopes that occur naturally, we just take the most common occurrence as the default by which the others are measured. Carbon-13 is naturally occurring in most organisms.

[The360Route]

@Mindbitesdotcom I don't understand if neutrons have mass nearly a zero, how they increase the weight of the C?

[vancouverkiz]

i believe you take the atomic mass, and then subtract the atomic number, and you get the neutron.

[myacclolable]

@vancouverkiz So If the weight is 6 and the number is 12 and you say 6 - 12 you get -6 :D..

[Anadance]

@PathofReason Neutrons are located in the nucleus. They are subatomic parts. Atoms are made of protons, neutrons, and electrons. protons and neutrons are located in the nucleus, and electrons just whirl about the outside of the atom.

que....?
