Answer :
To determine which elements are most likely in the same group of the periodic table, let's analyze the provided data focusing on the valence electrons, as elements in the same group on the periodic table usually share the same number of valence electrons.
Here is the detailed information about the five elements:
1. Aluminum (Al)
- Total electrons: 13
- Valence electrons: 3
- Year isolated: 1825
2. Boron (B)
- Total electrons: 5
- Valence electrons: 3
- Year isolated: 1808
3. Carbon (C)
- Total electrons: 6
- Valence electrons: 4
- Year isolated: 1803
4. Gallium (Ga)
- Total electrons: 31
- Valence electrons: 3
- Year isolated: 1875
5. Germanium (Ge)
- Total electrons: 32
- Valence electrons: 4
- Year isolated: 1886
Let's consider the valence electrons to determine group memberships:
- Aluminum (Al) has 3 valence electrons.
- Boron (B) has 3 valence electrons.
- Carbon (C) has 4 valence electrons.
- Gallium (Ga) has 3 valence electrons.
- Germanium (Ge) has 4 valence electrons.
From this information, we can observe the following:
- Aluminum (Al), Boron (B), and Gallium (Ga) each have 3 valence electrons. Elements with the same number of valence electrons tend to be in the same group.
Therefore, Aluminum, Boron, and Gallium are most likely to belong to the same group in the periodic table because they all have the same number of valence electrons, which supports the typical organization of elements in the periodic table.
