Determine the identity of the daughter nuclide from the electron capture by 3517cl. determine the identity of the daughter nuclide from the electron capture by . 4019k 3218ar 3516s 3215p 3718ar

         

Explanation:

When the nucleus of an atom captures and electron, such electron combines with a proton and forms a neutron. Thus, the mass number remains the same (just a proton has been converted into a neutron) but the atomic number (the number of protons) decrease in one.

Then, the daughter nuclide will have the same mass number and the atomic number reduced in one.

The given parent isotope is    ,    which means that it has these features:

Chemical symbol: Cl Name of the element: chlorine  Mass number (the superscript to the left): 35  Atomic number (the subscript to the left): 17

And the daughter nuclide after the electron capture will be:

Mass number: 35 (the same of the parent nuclide)Atomic number: 17 - 1 = 16Identity: sulfur (search the element with atomic number 16 in a periodic table).Chemical symbol: SIdenity of the daughter nuclide using the isotope notation:

         

Hence, the answer is the third choice.

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

The correct answer is c b c a d
