When K-37 undergoes positron emission, what is the resulting atom?
natita [175]

Answer:

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.

Where it is on the periodic table

Explanation:

The properties of elements can be predicted by where it is located on the periodic table.

The periodic table is an arrangement of elements based on the their atomic numbers.

Arrangement of elements in the periodic table follows a systematic manner such that it now known that elements in the same vertical column have the same chemical properties.

Elements to left on the table are mostly metals. Those to the left are non-metals.

The position of an element on the periodic table determines its properties
