Here's the breakdown:
* Pb stands for lead (Pb is the chemical symbol for lead).
* NO₂ represents the nitrite ion.
* The subscript 2 outside the parenthesis indicates there are two nitrite ions in the compound.
Therefore, the correct compound name is Lead(II) Nitrite.
Here's why the name is Lead(II) Nitrite:
* Lead(II): Lead can have multiple oxidation states (charges). The Roman numeral "II" indicates that lead has a +2 charge in this compound.
* Nitrite: The nitrite ion (NO₂) has a -1 charge.
To balance the charges, we need two nitrite ions to balance the +2 charge of the lead ion.
