Final answer:
The name of Sn(NO₃)² is tin(II) nitrate, where 'Sn' represents tin with a +2 charge and 'NO₃' represents the nitrate ion.
Step-by-step explanation:
The name of the compound Sn(NO₃)² is tin(II) nitrate. In this compound, Sn stands for tin and has a +2 charge, indicated by the Roman numeral II. The polyatomic ion (NO₃)¹⁻ is known as nitrate. Since there are two nitrate ions needed to balance the charge of tin(II), the formula is written as Sn(NO₃)². The (II) indicates the oxidation state of tin in this compound.
