Understanding the Modern Periodic Table and Properties of Metals

This chapter explores the arrangement of the Modern Periodic Table, with elements ordered by increasing atomic number, and distinguishes between periods and groups. It delves into the physical properties of metals, which include malleability, ductility, and conductivity, as well as their chemical properties like reactivity and corrosion. The periodic table classifies elements into metals, non-metals, and metalloids, highlighting the unique characteristics and classifications of various groups, such as alkali metals and noble gases. Visual aids and interactive activities reinforce learning.

Presentation Transcript

  1. Chapter 3 Section 2 & 3

  2. Dmitri Mendeleev Russian scientist that arranged the elements in order of increasing atomic mass.

  3. The Modern Periodic Table • Is now arranged by increasing atomic number

  4. Horizontal rows are called PERIOD. G R O U Vertical rows are called Each group shares the same characteristics.

  5. Physical Properties of Metals • Malleable: material is one that can be hammered or rolled into flat sheets or other shapes • Ductile: material that can be pulled out or drawn into wire • Conductivity: ability to transfer heat or electricity to another object

  6. Pictures to Help Me Remember!! Malleability Conductivity Ductility

  7. Chemical Properties of Metals • Reactivity: the ease and speed at which an elements reacts with other elements or compounds • Corrosion: wearing away of a metal by a chemical change. Turns reddish- brown REACTIVITY This metal car is coated with rust after being exposed to air.

  8. The periodic table consists of metals, non- metals, and metalloids Metalloids are elements that have properties of non- metals and metals

  10. BRAIN BREAK Color your periodic table based on it being a metal, non- metal, or a metalloid

  11. Group 1- Alkali Metals • Very reactive • Shiny • Soft Potassium Sodium Lithium

  12. Group 2- Alkali Earth Metals • Hard • Conductor of electricity • Reactive but not as reactive as group 1 Magnesium & Aluminum Calcium

  13. Group 17- Halogens • Very reactive • Both useful and dangerous to humans Bromine & Silver Carbon & Fluorine Chlorine

  14. Group 18- Noble Gases • Unreactive because outer shell has 8 electrons

  15. Lanthanides • Soft • Malleable • Shiny • High conductivity • Used to make alloys • Alloys: mixture of metals

  16. Actinides • Only four occur naturally on Earth • Thorium, Protactinium, Actinium, Uranium • All of the elements heavier than Uranium (U) are artificially made in labs • Unstable
