Metal X could be located in Group 13 on the periodic table. The correct option is (3) Group 13
From the question,
We are to determine where metal X could be located on the periodic table.
The given chemical formula is X₂(SO₄)₃
To determine where X could be located on the periodic table, we will simply calculate the oxidation number of element X
Calculating the oxidation number of X in
X₂(SO₄)₃
2X + [6×3 + (-2×4×3)] = 0
2X + [18 + (-24)] = 0
2X + 18 -24 = 0
2X -6 = 0
2X = 6
∴ X = 6÷2
X = +3
Therefore, oxidation number of X is +3
Since the oxidation state of metal X is +3, it could be located in group 13.
(NOTE: The metals in group 13 have an oxidation state of +3)
Hence, metal X could be located in Group 13 on the periodic table. The correct option is (3) Group 13
