Elizabeth Wilkins · Answer 1

C) Ar-37

Explanation:

A positron is a positively charged electron. It has the same mass as that of an electron, but opposite charge. It is the counterpart of an electron.

The reaction involving the emission of a positron by k-37 would produce a Ar-37, which is an unstable isotope of Argon. In this emission, there must not be a particle loss or creation, the addition of the mass number and proton number on LHS must be the sane as that on RHS of the equation.

An isotope is ability of an element to exist in two or more forms with the same atomic number but different mass number.
