In the periodic table, elements are represented by abbreviations in boxes such as the one shown to the right for the element boron. Compare the information given in the periodic table representation of boron (at right) to the symbol of a specific boron atom (in the Model 2 simulation). What information about atomic composition of boron is clearly represented in both

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.

idk i'm not smart
