How can helium exist in three different forms

WebAt temperatures of about 100,000,000 to 200,000,000 K (1 to 2 × 10 8 K), three helium nuclei can fuse to form carbon. This reaction takes place in the following way: two helium nuclei combine to form an unstable isotope of beryllium , which has an extremely short life; rarely, a third helium nucleus can be added to form carbon before the beryllium decays .
