Understanding Atomic Number and Atomic Mass

[Bayanalmaa]

You explain what my teacher gave me in 1h leacture in few seconds THIS IS SO AMAZING

[dorians-world]

This was really helpful. You explained it so clearly in a few minutes! Great job

My dad remembers all of the atomic numbers and initials and atomic mass of the elements in the periodic table

Wow i learned more from a 2 minute youtube video rather than an hour of class

MASS NUMBER is the amount of protons + neutrons, while ATOMIC MASS is the average number of protons and neutrons for all natural isotopes of an element.

Omg thank you! P.s. I hate chemistry with a passion 🙃

Thanks for the video! It was extremely useful.

[jasonfrost]

This is the greatest Youtube video of all time!

Still confusing. The words “number” and “mass” are used interchangeably. More explanation should be given on why there is no difference between “number” (quantity) and “mass” (ie weight). Why is Atomic “Number” the “number” of protons while Atomic “Mass” is also the “number” of protons etc.

Should they not have used “Total Atomic Number” instead of “Atomic Mass”?

Is anyone else from Mrs. Austin or Mr. Norris' class?

If you're going to explain what an atomic number and atomic mass is, you might as well briefly describe what the word isotope means.

Problem: In order to understand this explanation you must first know what an isotope is. Therefore = fail.

im so sorry but it was so short u need to explain alittle
