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

the form of energy changes and the total energy increases0l

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.
