What is the number in scientific notation? 0.93 enter your answer in the box.

0.000000000093 in scientific  notation   is  9.3 x 10  ^-11

 explanation

Step  1 :  move the decimal place to the right to create  new  number which  is between 1 to 10  = 9.3

Step 2:  Determine the exponent  ( number of time you   moved the decimal) =  11 times = -11 since the decimal is  moved to the right.

Step 3:  write the number  into correct  form of scientific notation.

  = 9.3  x10 ^-11

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.
