Study Notes

Module Overview

Structured lessons with clear activities, questions, and discussions to aid understanding.
Each SLM (Self-Learning Module) consists of several parts guiding step-by-step discovery of the lesson.

Pre-tests and Post-tests

Pre-tests assess prior knowledge to determine readiness for the module.
Post-tests serve as self-checks of learning, providing answer keys for evaluation.

Teacher and Facilitator Support

Notes to Teachers included for strategies on assisting students in home-based learning.
Important to maintain cleanliness by not marking the SLM; use separate sheets for exercises and tests.

Module Content

Focus on the arrangement of elements and the characteristics of reactive and nonreactive metals.
Language used is accessible to accommodate varying student vocabulary levels.
Lessons include:
- Arrangement of Elements
- Reactive and Nonreactive Metals

Learning Objectives

Identify groups and periods in the Periodic Table.
Describe properties of metals, nonmetals, and metalloids.
Compare relative reactivity of metals.
Utilize the Periodic Table to predict chemical behavior of elements.

Groups and Properties of Metals

Group 1 elements: Alkali metals, very reactive, soft, malleable, with one valence electron.
Group 2 elements: Alkaline Earth metals, second most reactive, with two valence electrons.

Reactivity of Metals

Reactivity generally decreases from left to right across a period.
Metals arranged by reactivity show that potassium (K) is among the most reactive.
Elements in the same group have similar chemical properties due to the same number of valence electrons.

Testing Knowledge

Multiple-choice questions assess understanding of the Periodic Table and metal reactivity.
Questions include the identification of groups, properties of specific elements, and arrangement by reactivity.

Reactivity Series

Series of metals listed in order of decreasing reactivity: K, Na, Ca, Mg, Zn, Fe, H, Cu.
Recognizes that more reactive metals can displace less reactive metals in reactions.

Rusting

Fastest rusting occurs in the presence of iron, salt, and water.

Additional Activities

Activities designed to determine the reactivity of metals when combined with HCl or water.
Exercises that require analyzing reactions to determine if one metal can replace another in compounds.

Summary of Key Terms

Groups: Vertical columns on the Periodic Table.
Periods: Horizontal rows on the Periodic Table.
Reactivity Series: List ranking metals by their reactivity.

Conductivity

Metals are generally good conductors of heat and electricity, with varying levels of malleability and ductility.

Learning Reinforcement

Fill-in-the-blank activity to reinforce concepts of how chemists classify metals based on reactivity.
Interactive activities to solidify understanding of chemical reactions and properties of different metals.
