TEAS 7. Basic atomic structure Part 1

[@almacuellar99]

Professor Yu, your videos helped me prepare for the TEAS because I haven’t taken A&P 2 or biology yet. Thank you so so much!!! You put out such amazing videos.

Woohoo, I'm so glad to hear that! Thank you for letting me know - really appreciate your kind words! A&P 2 is really fun - I hope you will like it when you finally take it 😀

Hello Professor Yu, I don't understand the last question's answer. It says the sulfur isotope and I thought for isotopes the number of neutrons must be different but why is the neutron number the same as proton and electron? thank you.

[@professoryu5571]

Yeah, good question. In the question, there's only one sulfur isotope. And for this particular isotope, the number of neutrons is 16. The number of neutrons can be the same as the number of protons and electrons, not always but it could happen. A different sulphur isotope would be sulfur 34. For this isotope, atom#d doesn't change, still 16, but the # of neutrons would be 34-16=18. Now you can see that first, this second isotope has more neutrons than the other isotope. And second, #neutron is different than #atom. Hope this helps! :)
