Answer :
Given the facts about the five elements provided in the table and the resulting groups, let's analyze the elements based on their number of valence electrons to determine the correct grouping.
1. List of Elements with their Valence Electrons:
- Aluminum (Al): Valence Electrons = 3
- Boron (B): Valence Electrons = 3
- Carbon (C): Valence Electrons = 4
- Gallium (Ga): Valence Electrons = 3
- Germanium (Ge): Valence Electrons = 4
2. Grouping Based on Valence Electrons:
Group 1: Elements with 3 Valence Electrons
- Aluminum (Al)
- Boron (B)
- Gallium (Ga)
Group 2: Elements with 4 Valence Electrons
- Carbon (C)
- Germanium (Ge)
When analyzing the given elements based on their valence electrons, we can confirm the following groups:
- Group 1: Contains elements with 3 valence electrons: ['Aluminum', 'Boron', 'Gallium']
- Group 2: Contains elements with 4 valence electrons: ['Carbon', 'Germanium']
These groups are derived by observing the valence electron count of each element.
Thus, the answer to the problem of grouping these elements by their valence electrons is:
- Group 1: 'Aluminum', 'Boron', 'Gallium'
- Group 2: 'Carbon', 'Germanium'
