Question

What is the cosmic importance of unstable${}^{\mathbf{\text{8}}}\mathbf{\text{Be}}$?

Short answer

${}^{\text{8}}\text{Be}$ is an activated complex that fuses with alpha particles to form atoms with bigger nuclei.

Step-by-step solution

Definition of Concept

Electronegativity: An atom's chemical behavior in which it attracts the shared electron pair to itself is known as electronegativity. As the number of energy levels grows larger, electronegativity decreases.

Find the cosmic importance of unstable Be8 

In reactions, the unstable ${}^{\text{8}}\text{Be}$nuclei serve as activated complexes. This unstable nuclei is created when alpha particles fuse at a star's core. Different atoms such as ${}^{\text{12}}\text{C,}^{\text{16}}{\text{O,}}^{\text{20}}\text{Ne}$, and ${}^{\text{24}}\text{Mg}$can form when ${}^{\text{8}}\text{Be}$collides with other alpha particles.
