Nuclide Symbols: Atomic Number, Mass Number, Ions, and Isotopes

How do we represent an atom, with all of its protons, neutrons, and electrons? With nuclide symbols, of course! These show the type of element, as well as the atomic number, mass number, and electrical charge of an atom. That's all you need to know!

[@thegoodlydragon7452]

It amazes me that out of pure snobbery a lot of so-called "real educators" in the academy still snobbishly snub their noses at KZbin when KZbin actually often does a far better job educating people than they do. These chemistry videos are more informative and clear than A LOT of professors who drone on confusingly with their chicken scratch handwriting and a marker doodle or two. The clear graphics alone make it easier to follow, not to mention it's explained well. Many teachers are glorified educational KZbinrs, but with smaller audiences. It's like the professors are scribes at the dawn of the printing press, bitching about how vulgar it is that the words are stamped on the page rather than handwritten.

I'm taking Prep General Chemistry this summer in a 4/5 week college class so in Fall I can take General Chem. I haven't done chemistry or math since HS and I was so scared but these videos are helping a ton! I actually didn't learn how to calculate all these things because we didn't have a chem teacher until like MARCH so we had to scrunch everything and really only learned about the periodic table and different types of mixtures.

[@FreshSongs-AND-SOON-Politics]

The part that boggles me is: i.e., if 75 is the percent abundance of Cl 35, what is the point of 75 of 35. Wouldn't that be a percent of an individual atom? The math expression just seems so redundant to me. In my head (and I know this is not correct. The issue is I know how to do it correctly, but can't seem to computer the why), 75 percent should be multiplied by the total of a sample to predict how much of that samples mass belongs to Cl 35. Yet this is so obviously not what's going on.

Facts. I remember in my school days how I would look in the glossary of the science book to understand what the word meant and the definition was 30 other words that I didn't know what they meant. So I'd look up those and they had words I didn't know in their definitions too. Lol. So I'd do all that work and still have no idea what the words meant.

[@borttorbbq2556]

I learn something new I always wondered about why the atomic mass wasn't a whole number I never took a high school chemistry class so yeah. So far I've known most of this because I love science so I have been learning it over the years regardless. Figured I should probably take a look at an actual chemistry course type thing so I can have a bit better understanding in a more coherent way. One upside to being homeless is I have a lot of time on my hands so learning and refreshing one of my favorite subjects being science as a whole sounds good. But I'm sure as we go deeper I will start running into more that I don't know I've been teaching myself most of the basics but there's only so much you can do by self learning. And Dave makes amazing content so it works out

[@themexicanmullet9708]

So to find electrons you do the opposite of the sign in front of the charge to the proton

[@carultch]

The net charge of the protons and electrons needs to add up to the net charge of the ion. Protons add charge, electrons subtract charge. Protons identify the element, while electron count is flexible. There generally tend to be certain ions that are more likely to form than others.

[@user-nc5wc7dh7l]

So is 'Nuclide' an umbrella term for isotopes, ions and elemental nucleus?

[@ProfessorDaveExplains]

pretty much!

[@PETERBAKR]

In your review question, I get how you got all of the answers except the Mass for Sn, I have looked at several periodic tables and they say that Sn mass number =118 not 112 as you put into the answer table....I am missing something , can you explain how you arrived at mass number of 112, please.

[@ProfessorDaveExplains]

so the atomic masses on the periodic table are average atomic masses, every element has atoms of different mass, these are called isotopes. so like carbon's atomic mass is a little over 12 because it's the average of all the 12-C, 13-C, and 14-C that there are. watch this one more time!

[@ssthokal7357]
