help! i suck at chem lol Identify the isotope using hyphen notation with the given composition: 76 protons, 113 neutrons, 76 electrons
justus:
Is there options?
mimih:
nope
mimih:
okay give me a moment to process this real quick
justus:
Ok
justus:
Whats the name of the element?
mimih:
osmium
mimih:
so then wouldnt the neutrons in the isotope be 114
justus:
One sec
mimih:
okay
justus:
I think it would be Osmium-113
justus:
Also you wrote 113 are you sure its not 114?
mimih:
well the question has is as 113
justus:
For the number of neutrons
justus:
Okay then we will use it
mimih:
so Osmium-113
justus:
I think this will help you Atomic number=number of protons Mass number=the sum of the protons and the neutrons Isotopes=different versions of the same element, same number of protons Hyphen notation=name of element- mass number Mass number - atomic number= number of neutrons
justus:
Yes I believe so
mimih:
okay that makes sense, thank you!
justus:
No problem!
justus:
So basically your mass number is 189 Your atomic number is 76
mimih:
yes
justus:
Let me know if you need more help :)
mimih:
will do!
justus:
I took chemistry last year so im kind of still trying to comprehend but I might be able to help you
mimih:
thanks! i honestly dont like any science at all. also i am looking at the different types of isotopes but there isnt a Osmium-113
justus:
Your welcome! I don't like the science field either. Hmm
mimih:
i just searched up something and it said usually the isotope is the number that is closest to the atomic mass
justus:
Your right, thats odd
mimih:
i think it would be osmium-190 because there isnt a 189
justus:
Thats true also when I searched up the neutrons of osmium I found that it was 114
justus:
So it must be what you said
mimih:
yeah I think my teacher put it in wrong on accident not sure tbh
justus:
Maybe
mimih:
i hope it is lol its for corrections
justus:
Haha hopefully
mimih:
anyways thank you, I wouldnt have figured it out alone:)
justus:
I gotchu! It was fun working with you
mimih:
likewise!
justus:
Did you get it right? @mimih
mimih:
no havent submitted yet, the test is kind of long I plan on finishing it tonight and the score will come up!
justus:
Ooh damn. Good luck
justus:
You can do it!
mimih:
thanks!
mimih:
okay so i was going through my tests and i just remembered that this was for a test correction and not a test, ive been so busy with HS classes and college so I confuse things all the time. Im about to check now if I got it right! @justus
mimih:
Okay so I got the right answer but I wasnt able to back it up with sufficient details so I didnt get the points:( but I got the points for the other corrections
justus:
Oh im sorry about that.
mimih:
its alright, thank you for the help tho!
