Fusion processes, like combining two deuterons to form a He nucleus are impossible at ordinary temperatures and pressure. The reasons for this can be traced to the fact: (a) nuclear forces have short range. (b) nuclei are positively charged. (c) the original nuclei must be completely ionized before fusion can take place. (d) the original nuclei must first break up before combining with each other.
