What are The Groups in The Periodic Table?
Updated: February 23, 2025
Summary
The video introduces the concept of groups and columns in the periodic table, showcasing how elements with similar properties are grouped together. It explains the significance of valence electrons in determining an element's behavior, with Group 1 having one outer electron and Group 2 having two. Transition metals, located in the middle blocks, are explored for their conductivity, high melting points, and unique characteristics like forming colored compounds. Halogens are highlighted as highly reactive elements, while noble gases stand out for their stability that other elements seek to achieve through reactions.
