In the third equation, the oxygen with atomic weight 16 undergo alpha decay and produce C₆¹³ . The alpha particle emitted is also called helium nuclei. During this decay some gamma radiations also produce as a byproduct.

<h3>What is Nuclear decay reaction ?</h3>

It is also called as radioactive decay during which an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements.

The atom emit the alpha particles consist of two proton and two neutrons. Which is also called Helium nuclei.

When atom undergoes the alpha emission the original atom convert into the atom having mass number 4 less than and atomic number 2 less than the starting atom.

Alpha radiations can travel in a short distance.

These radiations can not penetrate into the skin or clothes.

These radiations can be harmful for the human if these are inhaled.

These radiations can be stopped by a piece of paper.

Hence, the oxygen with atomic weight 16 undergo alpha decay and produce C₆¹³  and an alpha particle (He)

Direct electron transfer from a singlet reduced species to a triplet oxidizing species is quantum-mechanically forbidden

Direct electron transfer from a a singlet reduced species to a triplet oxidizing species is quantum-mechanically forbidden.

<h3><u>Transfer from singlet to triplet:</u></h3>
  • Either an excited singlet state or an excited triplet state will occur when an electron in a molecule with a singlet ground state is stimulated (through radiation absorption) to a higher energy level.
  • All electron spins in a molecule electronic state known as a singlet are coupled.
  • In other words, the ground state electron and the stimulated electron's spin are still coupled (a pair of electrons in the same energy level must have opposite spins, per the Pauli exclusion principle).
  • The excited electron and ground state electron are parallel in a triplet state because they are no longer coupled (same spin).
  • It is less likely that a triplet state would arise when the molecule absorbs radiation since excitation to a triplet state necessitates an additional "forbidden" spin transfer.
