OpenStudy (perl):

OpenStudy (anonymous):

Just the clues that go with the periodic table

OpenStudy (anonymous):

OpenStudy (anonymous):

@ganeshie8 can you help me?

OpenStudy (anonymous):

@undeadknight26 can you help me?

undeadknight26 (undeadknight26):

Do you know how to navigate a periodic table?

undeadknight26 (undeadknight26):

hello?

OpenStudy (anonymous):

Yeah

undeadknight26 (undeadknight26):

kk then the nonmetals! where r they?

OpenStudy (anonymous):

In the yellow

undeadknight26 (undeadknight26):

then find the one with the second atomic mass!

OpenStudy (anonymous):

Yeah I really didn't think of that before!!

undeadknight26 (undeadknight26):

lol...hahah

OpenStudy (anonymous):

How do I get atomic mass

undeadknight26 (undeadknight26):

botom number.

OpenStudy (anonymous):

Ok that can't be because I have already answered this question and I chose atomic number 35 and I got it wrong!!

OpenStudy (anonymous):

OK well I knew I wasn't trying to get the biggest

undeadknight26 (undeadknight26):

sorry lol.

OpenStudy (anonymous):

But it can't be 34 because I have something in there and I got that one right.

OpenStudy (anonymous):

Hello?

OpenStudy (perl):

hi

OpenStudy (perl):

the periodic table gives you relative atomic mass, because there are isotopes with different number of neutrons

OpenStudy (perl):

the 'mass' of an atom comes almost entirely from the neutrons and protons, which weigh about the same. the electrons have negligible weight in comparison to the neutrons and protons. so practically all the mass of an atom comes from the nucleus.

OpenStudy (perl):

so which number are you doing, specifically?

OpenStudy (anonymous):

Totally confused but I just gave ya'll the wrong question clues, here are the right ones.

OpenStudy (the_fizicx99):

OMG I did this last year!! Haha xD

OpenStudy (anonymous):

lol

OpenStudy (the_fizicx99):

Did you finish it?

OpenStudy (anonymous):

Yeah I got 100%

OpenStudy (the_fizicx99):
