What are Isotopes?

To see all my Chemistry videos, check out
socratic.org/chemistry
We'll learn about what isotopes are and how to write atomic number and mass number in isotope notation. We talk about a simple analogy with cars to explain this tutorial. Isotopes are versions of an atom or an element that have the same number of protons, but different numbers of neutrons. Isotopes and isotope notation are particularly important in nuclear chemistry.

There's a special place in heaven for people that make videos like this

[@ducks4life840]

Hell?

[@user-vz3lu1ek1t]

People please, it doesn't matter whether he believes in heaven or not. What matters is that he's educating the world with these videos, and that's all you have to know.

[@user-vz3lu1ek1t]

By the way, being an atheist is neither good nor bad. Well, it's the same case with being a religious one too. As long as you're a human, it's acceptable. To educate the world is indeed what a human should do.

Exam: what is Isotope? Me: well we have a lemona-G, a lemona-GX, and a lemona-GXL

[@_____J______]

Isotopes are atoms that have the same number of protons and electrons, but a different number of neutrons. Changing the number of neutrons in an atom does not change the element. Atoms of elements with different numbers of neutrons are called "isotopes" of that element. The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons. Atoms fit together with other atoms to make up matter. Protons are tiny particles inside the center of an atom. They they make up most of the weight of an atom, but they are still very small. In fact, if an atom was the size of a baseball stadium, each of its protons would still only be the size of a marble! The electron is a negatively charged particle that spins around the outside of the nucleus. Electrons are attracted to the nucleus by the positive charge of the protons. Electrons are much smaller than neutrons and protons. About 1800 times smaller! In case someone is really for exam here

[@stanleyshack26]

Whyms you are right is he simplify Isotopes better than my biology book. The schools and colleges books are so complex that the average student cannot understand these books. Thats why some people come to youtube and get tutorials to learn what is written in these books. These books need to be simplify so more people learn.

[@stanleyshack26]

He simplify Isotopes very good

[@stanleyshack26]

Everything cannot be simplify but a lot of things in books in school and college need to be simplify so more people can get a better understanding. Things need to change in education. Its time far a Revolution in education.

[@LynxMajic]

crash course is like a revision for what you took, thats why its so fast and tries to put as much information in a small amount of time. this should be what you watch before the exam, not what you study from.

Okay, I had to comment. I have been having the hardest time doing Chemistry. I've been having so many breakdowns from it and the book/teacher was just not making sense in any possible way. I would spend hours going over and over my book, again and again, trying to get it and watching video after video and reading article after article. Just to understand. I came over your videos today and I cannot tell you how much I understand now. I feel so incredible. I have been freaking out all day on how much I understand chem now. It all is coming together. And I just wanted to thank you for that. You are seriously not making me want to quit school now.

If H2O is the formula for water, what is the formula for ice? H2O cubed.

[@blackwatch4471]

Actually its the same formula. The only difference between water and ice is the bonding between the molecules,the molecules in the ice have stronger bonding,that's what makes it a solid,while in water they have weaker bonding and that's what makes it a liquid.
