The atomic mass of common krypton is 84, and its atomic number is 36. krypton-82 has how many neutrons within each isotope? a. 46 b. 48 c. 118 d. 120

Option B, There are 48 neutrons within each isotope

Explanation:

As we know ,

Mass number (M)  is equal the sum of atomic number (A) and neutrons (n)

Mathematically, it can be represented as -

Given,

Atomic Mass (M)

Atomic Number (M)

Substituting the given values in above equation, we get -

Option B is correct
