Metalloid

Summary: The elements near the red line in the Periodic Table, like germanium and silicon, are metalloids. Their properties are between those of metals and non-metals. Most metalloids are shiny. They are semiconductors of electricity. This means they are between conductors and insulators. Tags: science student-book-7 chemistry Created: 2026-05-21 Last Updated: 2026-05-21
