what is the highest atomic weight
Hello dear student,
As you have asked for the highest atomic weight that means the heaviest atom which is present in periodic table. So ununoctium is the heaviest atom which is present and this element is man made. while the naturally occurring element with the highest atomic weight is uranium. Atomic weight 238.0298
I hope this was helpful
Thank you
The highest atomic weight is of ununoctium but it is the man made element ,the heaviest naturally occurring element is uranium whose atomic number is 92 and atomic weight is 238.0289
