What is the formula for sodium nitride?
Sodium is an element in group 1 of the periodic table. As such, it will form an electron by losing a single electron to form a
Nitrogen is an element in group 5 of the periodic table. When it forms the nitride ion, it gains three electrons to form a
In ionic compounds, the charges of constituent ions must balance. This can be achieved by having three sodium ions per nitride ion. Therefore, the formula of sodium nitride is
It lacks a boiling point because of this. Since ionic compounds have very high melting and boiling points as a result of the strong electrostatic attraction between oppositely charged ions that holds them together, sodium nitride should be no different; however, it will decompose as shown at around
