topic: basics of the periodic table
learning objectives:
by the end of this assignment, you should be able to:
describe how the periodic table is organized
identify element groups and periods
understand trends such as atomic number, atomic mass, and reactivity
use the periodic table to determine basic properties of elements
part 1: vocabulary matching (5 points)
match the term to its correct definition.
term definition

1. period a. a horizontal row on the periodic table
2. group (or family) b. an element that is usually shiny, conducts electricity, and is malleable
3. atomic number c. a vertical column of elements with similar properties
4. metal d. a type of element that is dull, brittle, and does not conduct electricity well
5. nonmetal e. the number of protons in an atoms nucleus

part 2: periodic table questions (10 points)
use your periodic table to answer the following questions:

Explanation:

Step1: Match definition to term for 1

A horizontal row on the periodic table is called a period. So 1 matches A. Period.

Step2: Match definition to term for 2

An element that is usually shiny, conducts electricity, and is malleable is a metal. So 2 matches D. Metal.

Step3: Match definition to term for 3

A vertical column of elements with similar properties is a group (or family). So 3 matches B. Group (or Family).

Step4: Match definition to term for 4

A type of element that is dull, brittle, and does not conduct electricity well is a non - metal. So 4 matches E. Nonmetal.

Step5: Match definition to term for 5

The number of protons in an atom's nucleus is the atomic number. So 5 matches C. Atomic Number.

Answer:

1. A. Period
2. D. Metal
3. B. Group (or Family)
4. E. Nonmetal
5. C. Atomic Number
