Explanation:

• Question 5: Silicon is a metalloid. It has properties that make it suitable for electronic applications. Oxygen is a non - metal, carbon (in most common forms like graphite and diamond) has different properties (graphite is a conductor but diamond is an insulator; neither is a metalloid in the context of electronic ride controls in the typical sense), and iron is a metal.
• Question 6: Non - metals are generally brittle (they break easily) and non - conductive (do not conduct electricity well). Metals are often heavy (but this is not a property of non - metals).

Answer:

Question 5: Silicon
Question 6: Brittle and non - conductive
