For the same set of elements, identify the Main Group (Group A) number that best identifies the element's family location on the periodic table. (6 points)

Question

Oxygen, Calcium, Phosphuros, Argon, Chlorine, Boron.

VIA(6A), IIA(2A), VA(5A), VIIIA(8A), VIIA(7A), IIIA(3A)

Answer 1

To classify the given elements and identify their Main Group (Group A) numbers, we can categorize each element as follows:

1. Oxygen (O) - This element is in Group 16, which corresponds to VIA (6A).
2. Calcium (Ca) - This element is in Group 2, which corresponds to IIA (2A).
3. Phosphorus (P) - This element is in Group 15, which corresponds to VA (5A).
4. Argon (Ar) - This element is in Group 18, which corresponds to VIIIA (8A).
5. Chlorine (Cl) - This element is in Group 17, which corresponds to VIIA (7A).
6. Boron (B) - This element is in Group 13, which corresponds to IIIA (3A).

Here is the summary of each element with its corresponding group:

• Oxygen: VIA (6A)
• Calcium: IIA (2A)
• Phosphorus: VA (5A)
• Argon: VIIIA (8A)
• Chlorine: VIIA (7A)
• Boron: IIIA (3A)
