- Name Date Class 3-4 Apply The Carbon-Nitrogen Cycle Hydrogen nuclei are involved in a process known as the carbon-nitrogen cycle. The six reactions in this decay series are presented below. The net result of the carbon-nitrogen cycle is that four hydrogen atoms are combined to produce one helium atom. Reactions 2 and 5 involve decay particles called positrons ( e ). Positrons are essentially positively charged beta particles.
