In reaction A, each sodium atom gives one electron to a chlorine atom. In reaction B, an isotope of oxygen decays to form an isotope of nitrogen. Which statement best describes the energy that is released per gram by these reactions?
A. Reaction A releases more energy than reaction B releases.
B. Reaction B releases more energy than reaction A releases.
C. Reaction A and reaction B release equal amounts of energy.
D. Neither reaction A nor reaction B releases energy.
Can someone help pleasee

Option B. Reaction B releases more energy than reaction A.

Explanation:

Answer is B. Reaction B releases more energy than reaction A.

Any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights. Isotopes of a single element possess almost identical properties.

Radioactive isotopes have an unstable combination of protons and neutrons, so they have unstable nuclei. Because these isotopes are unstable, they undergo decay, and in the process can emit alpha, beta and gamma rays.

Oxygen-13 is an unstable isotope of oxygen. It consists of 8 protons and electrons, and 5 neutrons. It has a spin of 3/2-, and a half-life of 8.58 ms. Its atomic mass is 13.0248 . It decays to nitrogen-13 by electron capture, and has a decay energy of 17.765 Mev.
