🔬 Part 1: Understanding Groups and Periods

1. What are groups in the Periodic Table?

Horizontal rows of elements

Vertical columns of elements

Elements with the same atomic number

Elements with similar mass

2. What are periods in the Periodic Table?

Vertical columns of elements

Horizontal rows of elements

Groups of metals only

Groups of non-metals only

3. Elements in the same group have similar:

Chemical properties

Number of outer shell electrons

Reactivity patterns

Atomic mass

📊 Part 2: Identifying Groups and Periods

4. Complete the following statements about the Periodic Table:

a) Group 1 elements are called _____________ metals and they become _____________ reactive as you go down the group.

b) Group 17 elements are called _____________ and they are very _____________ non-metals.

c) Group 18 elements are called _____________ gases and they are mostly _____________.

5. Match each element group with its correct properties:

1. Group 1 (Alkali metals)

2. Group 17 (Halogens)

3. Group 18 (Noble gases)

A. Very unreactive, stable

B. Very reactive metals

C. Very reactive non-metals

🧪 Part 3: Periodic Trends

6. Describe what happens to metallic character as you move from left to right across Period 2:

7. Why do elements in the same group have similar chemical properties?

They have the same atomic mass

They have the same number of outer shell electrons

They are all metals

They were discovered at the same time

8. Draw simple Bohr model diagrams showing the electron arrangement for two Group 1 elements (Lithium and Sodium):

🎯 Part 4: Applying Your Knowledge

9. If you discovered a new element that belonged to Group 1, predict three properties it would likely have:

10. Complete this table about Period 2 elements:

Element: Lithium → _______ → Boron → _______ → Nitrogen → _______ → Fluorine → _______

Type: Metal → _______ → Metalloid → _______ → Non-metal → _______ → Non-metal → _______

11. Explain how scientists use the organisation of the Periodic Table to predict element properties:
