The element with 32 electrons is Germanium.
Understanding Germanium
In a neutral atom, the number of electrons is equal to the number of protons, which defines the element's atomic number. Therefore, an element with 32 electrons must have an atomic number of 32. This element is Germanium, symbolized as Ge.
Germanium is a fascinating element classified as a metalloid, meaning it exhibits properties characteristic of both metals and nonmetals. Its position on the periodic table—specifically in Group 14, between silicon and tin—gives it unique semiconductor capabilities, making it indispensable in various technological applications.
Key Properties of Germanium
Germanium possesses several distinct physical and chemical properties that make it valuable. Below is a summary of some of its fundamental characteristics:

- Catalysts: It serves as a catalyst in polymerization reactions, particularly in the production of polyethylene terephthalate (PET).
Germanium in the Periodic Table
Germanium sits in the 4th period and Group 14 of the Periodic Table of Elements. Its placement indicates its electron configuration, specifically how its 32 electrons are arranged in shells, which dictates its chemical reactivity and physical properties. Being in the same group as carbon and silicon, it shares some chemical similarities but also exhibits metallic characteristics due to its larger atomic size and weaker hold on its valence electrons.
