Answer:
–2
Explanation:
Data obtained from the question:
Number of electron = 16
Valence electron = 6
Now, let us write the electronic configuration for sulphur. This is illustrated below:
1s2 2s22p6 3s23p4
From the above, we can see that sulphur will be needing 2 extra electrons to complete its octet configuration. Therefore, the oxidation number of the sulphur will be –2.
The minus sign indicate that the sulphur will accept 2 electrons to complete its octet configuration

Answer:
5.82 moles of sodium will produced.
Explanation:
Given data:
Mass of sodium azide = 378.3 g
Moles of sodium produced = ?
Solution:
Chemical equation:
2NaN₃ → 2Na + 3N₂
Moles of sodium azide:
Number of moles = mass/ molar mass
Number of moles = 378.3 g/ 65 g/mol
Number of moles = 5.82 mol
Now we will compare the moles of sodium azide and sodium.
NaN₃ : Na
2 : 2
5.82 : 5.82
If by Period you mean Column, they share the same amount of electrons in their outer shell.
