Third Quarter: Tala High School

This document provides a detailed lesson plan for a unit on groups and periods in the periodic table. The lesson objectives are to define groups and periods, determine the classification of elements as metals, semimetals or non-metals, and understand the importance of the periodic table's organization. Students will learn that the periodic table is arranged by atomic number into horizontal periods and vertical groups. Through activities identifying puzzle pieces to complete a periodic table and classifying elements into their proper groups and periods, students will understand the classifications of metals, semimetals and non-metals and how the periodic table's organization helps scientists.

UNIT 3: Module 2: Groups and Periods


I. OBJECTIVES
A. Content Standards
B. Performance Standards
C. Learning 1. Define groups and periods.
Competencies/ Specific 2. Determine the metal, semimetal and non-metal
Objectives elements based on the table presented.
3. Infer what will happen if we don’t have groups and
periods.
II. CONTENT
A. Subtopic Metals, Semimetals and Non-metals
B. Concepts  The periodic table is arranged in order of atomic
number
 A period is a horizontal row of the periodic table.
 A group is a vertical row of the periodic table.
Group 1 (Alkali Metals), Group 2 (Alkaline Earth Metals)
Group 13 (Boron Group), Group 14 (Carbon Group)
Group 15 (Nitrogen Group), Group 16 (Chalcogens),Group
17 (Halogens), Group 18 (Noble Gases)
METALS
In the periodic table, you can see a stair-stepped line
starting at Boron (B), atomic number 5, and going all the
way down to Polonium (Po), atomic number 84. Except for
Germanium (Ge) and Antimony (Sb), all the elements to the
left of that line can be classified as metals.
NON-METAL
Except for the elements that border the stair-stepped
line, the elements to the right of the line are classified as
nonmetals (along with hydrogen). Nonmetals have properties
opposite those of the metals.
METALLOIDS
The elements that border the stair-stepped line are
classified as metalloids. The metalloids, or semimetals,
have properties that are somewhat of a cross between
metals and nonmetals
