Question

How do you write the formula of tin (II) nitride?

Answer 1

Hint The chemical symbol to represent tin is ‘Sn’ and the chemical symbol which is used to represent nitrogen is ‘N’. we should know the oxidation state of the individual atoms to write the chemical formula of the given compound.

Complete step by step answer:
- In the question it is asked to write the formula of tin (II) nitride.
- There are two ions in the given chemical name, they are tin (II) and nitride.
- By combining tin (II) and nitride the chemical tin (II) nitride is going to form.
- Tin (II) has a ‘+2’ charge while the nitride has a ‘-3’ charge.
- In the given compound tin (II) nitride the total charge of ‘+6’ for three tin atoms are going to balance with a total charge of ‘-6’ for the two nitrogen atoms.
- Therefore the formula to represent tin (II) nitride is $S{n}_3{N}_2$ .
- Means there are three tin atoms and two nitrogen atoms are present in the molecular formula of tin (II) nitride.

Additional information:
- Tin (II) nitride is also called stannous nitride.
- The molecular weight of the stannous nitride is 384.
- Tin (II) nitride has an overall charge or net charge of zero on it.

Note: We should know which atoms are involved in the chemical name before writing the chemical formula for it. We should know the oxidation state of the individual atoms involved in the chemical name.
