Question
Which of the following is NOT true of non-metals?Athey are poor conductors of heat Bthey react with dilute acids to give hydrogen gas Cthey usually have low melting and boiling points Dthey are not malleable or ductile
Solution
The statement that is NOT true of non-metals is B: they react with dilute acids to give hydrogen gas.
Here's why:
A. Non-metals are indeed poor conductors of heat. This is a characteristic property of non-metals.
B. It is generally metals, not non-metals, that react with dilute acids to produce hydrogen gas. This statement is not true for non-metals.
C. Non-metals usually do have low melting and boiling points. This is another characteristic property of non-metals.
D. Non-metals are not malleable or ductile. They are typically brittle in their solid state. This is also a characteristic property of non-metals.
