Metals, Nonmetals, and Metalloids Overview

Lesson 3-3: Metals Location in Periodic Table • Periods = rows; Groups/Families

= columns • Metals = left side + center • Most reactive metals: Group 1

(alkali), then Group 2 (alkaline earth) • Transition metals = middle section

Classification of Metals • Alkali metals (G1) • Alkaline earth

metals (G2) • Transition metals (G3–12) • Lanthanides & Actinides (bottom

rows) Physical Properties • Shiny (luster) • Good conductors • Malleable & ductile

• High melting points • Solid at room temp (except mercury) Chemical Properties • Lose electrons

→ form positive ions (cations) • React with nonmetals (ex: rust) • Reactivity increases
