The relative abundance of magnesium is related to the fact that it is easily built up in supernova stars from a sequential addition of three helium nuclei to carbon (which in turn is made from three helium nuclei).
Kelimpahan relatif magnesium berhubungan dengan kenyataan bahwa ia mudah terbentuk dalam bintang supernova dari penambahan sekuensial tiga inti helium kepada karbon (yang pada gilirannya terbuat dari tiga inti helium).
