Web18 de ago. de 2024 · Because the first shell can only hold a maximum of 2 electrons, the third electron must go into the second shell. Therefore the lithium (Li), which has three total electrons, will have two electrons in the first shell and one electron in the second shell. Notice that lithium is the first element in the second row of the periodic table. 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.

How can helium exist in three different forms

WebFor helium-3 to form a superfluid, it must be cooled to a temperature of 0.0025 K, or almost a thousand times lower than helium-4 (2.17 K). This difference is explained by quantum statistics , since helium-3 atoms are fermions , while helium-4 atoms are bosons , which condense to a superfluid more easily.
