*overall atomic mass is the sum of protons and neutrons. Another lesson learned

OpenStudy (anonymous):

for isotopes you add at the ending the atomic mass for example carbon-14 just to give you an idea of how this works.

OpenStudy (anonymous):

would it be lithium

OpenStudy (anonymous):

atomic number reveals how many protons there are from periodic table

OpenStudy (anonymous):

Yeah it's an isotope of lithium

OpenStudy (anonymous):

since it has 7 neutrons..... the answer is?

OpenStudy (anonymous):

lithium-10

OpenStudy (welshfella):

lithium 7

OpenStudy (welshfella):
