Q24.92P - Chemistry: Molecular Nature Of Matter And Change

Question

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

Step-by-Step Solution

Answer

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

Step 1: 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.

Step 2: Find the cosmic importance of unstable Be 8

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.
