Interactive periodic table worksheet for learning about main group elements and their characteristics.

Let’s solve this step by step.

We’re working with the periodic table and learning how to match groups (like 1A, 2A, etc.) with their family names, valence electrons, charges, and descriptions.

Part B: Match group numbers to family names

Looking at the colored periodic table in the image:

- 1A is labeled “Alkali Metal Family” → so 1A = Alkali Metals
- 2A is labeled “Alkaline Earth Metal Family” → so 2A = Alkaline Earth Metals
- 3A is labeled “Boron Family” → so 3A = Boron Family
- 4A is labeled “Carbon Family” → so 4A = Carbon Family
- 5A is labeled “Nitrogen Family” → so 5A = Nitrogen Family
- 6A is labeled “Oxygen Family” → so 6A = Oxygen Family
- 7A is labeled “Halogens Family” → so 7A = Halogens
- 8A is labeled “Noble Gas Family” → so 8A = Noble Gases

*(Note: Sometimes 8A is also called Group 18 or Noble Gases — same thing.)*

Part C: Match descriptions to families

Let’s go one by one:

1. “Very reactive, 7 valence e-, -1 charge, tend to bond with elements in group 1”

→ 7 valence electrons? That’s Group 7A (Halogens). They gain 1 electron to get a -1 charge. They love bonding with Group 1 (which loses 1 electron).
✔ Answer: Halogens

2. “Low electronegativity, 2 valence e-, +2 charge, tend to bond with oxygen family”

→ 2 valence electrons → Group 2A (Alkaline Earth Metals). They lose 2 electrons → +2 charge. Oxygen family is 6A — they often form compounds like MgO, CaO, etc.
✔ Answer: Alkaline Earth Metals

3. “Have complete valence electron shells, are very unreactive, charge of 0”

→ Complete shells = full outer layer → that’s Noble Gases (Group 8A). They don’t react much and have 0 charge.
✔ Answer: Noble Gases

4. “Highly reactive, +1 charge, 1 valence e-, less dense than other metals”

→ 1 valence electron → Group 1A (Alkali Metals). They lose 1 electron → +1 charge. They’re soft and light (less dense) compared to other metals.
✔ Answer: Alkali Metals

5. “Very hard, usually shiny, ductile, malleable, can have more than one cation charge”

→ This describes transition metals! They’re in the middle block (yellow area), and many can form multiple positive charges (like Fe²⁺ and Fe³⁺).
✔ Answer: Transition Metals
