Thinking about the nitrides and carbides of the Group 1 elements, in what way does lithium differ from other elements of this group?
A) Only Li reacts directly with nitrogen and carbon to produce a nitride and a carbide respectively
B) Lithium nitride and carbide are basic, others are neutral.
C) Lithium nitride and carbide are soluble, the others are not.

Lithium is unique among Group 1 elements because it can directly react with nitrogen and carbon to form a nitride and a carbide, respectively, due to its small size and high polarizing power. Other Group 1 elements do not directly form these compounds under normal conditions.
