Respuesta :

The correct answer would be A. The number of neutrons present in Krypton-82 would be 46. The atomic number of an atom represents the number of protons present while the mass number is the sum of the neutrons and protons in the atom. The mass number for the given atom is 82. So, 82-36 = 46 neutrons present.

Answer:

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 -

[tex]M = A+ n[/tex]

Given,

Atomic Mass (M) [tex]= 84[/tex]

Atomic Number (M) [tex]= 36[/tex]

Substituting the given values in above equation, we get -

[tex]84 = 36 + n\\n = 84 -36 \\n = 48[/tex]

Option B is correct
