What will be oxidation state of Sc in `ScC_(2)` ?

Answer

To determine the oxidation state of Scandium (Sc) in Scandium carbide (ScC₂), we can follow these steps:

### Step 1: Understand the compound
Scandium carbide is represented as ScC₂, which indicates that there is one Scandium atom and two Carbon atoms in the compound.

### Step 2: Determine the oxidation state of Carbon
In most compounds, Carbon typically has an oxidation state of -4 when it is in the form of carbide (C²⁻). Therefore, in ScC₂, the oxidation state of the two Carbon atoms can be calculated as:
\[ \text{Oxidation state of 2 C} = 2 \times (-4) = -8 \]

### Step 3: Set up the equation for the oxidation state of Sc
Let the oxidation state of Scandium be \( x \). The overall charge of the compound is neutral (0). Therefore, we can set up the equation as follows:
\[ x + (-8) = 0 \]

### Step 4: Solve for the oxidation state of Sc
Rearranging the equation gives:
\[ x - 8 = 0 \]
\[ x = +8 \]

### Step 5: Conclusion
Thus, the oxidation state of Scandium in Scandium carbide (ScC₂) is +8.
