Answer: I think the answer is Cesium (Cs)
Explanation:
A half-filled 6s subshell would be 6s^1
According to the illustration, the vanadium (V) oxide would be a catalyst.
<h3>What are catalysts?</h3>
Catalysts are substances that are utilized in reactions that are not themselves consumed in reactions but only speed up the rate of the reactions.
Catalysts speed up the rate of reactions by lowering the activation energy of the reactants.
Sulfur dioxide reacts with oxygen to produce sulfur trioxide. The vanadium (v) oxide is not consumed in the reaction. Thus it only serves as a catalyst.

Explanation:
A chemical reaction equation that contains same number of atoms on both reactant and product side is known as a balanced chemical reaction equation.
For example,
Here, number of reactant molecules are as follows.
Na = 2
S = 2
Cd = 1
O = 4
Number of product molecules are as follows.
Na = 2
S = 2
Cd = 1
O = 4
As there are already equal number of atoms on both reactant and product side. Hence, the reaction equation is balanced.
Also, in this reaction both and are present as aqueous solution. And, CdS is the precipitate that is formed as it is the insoluble solid that forms.
is present in aqueous state.
