The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Elements**: The elements in question are Boron (B), Silicon (Si), and Germanium (Ge). 2. **Classify the Elements**: To classify these elements, we need to refer to their positions on the periodic table. Boron is located in group 13, Silicon in group 14, and Germanium in group 14 as well. 3. **Determine the Properties**: - Metals are typically good conductors of heat and electricity, have high melting and boiling points, and are malleable and ductile. - Non-metals are usually poor conductors, have lower melting and boiling points, and are brittle in solid form. - Metalloids exhibit properties of both metals and non-metals. 4. **Identify Metalloids**: Boron, Silicon, and Germanium are classified as metalloids because they possess characteristics of both metals and non-metals. They are found along the zig-zag line on the periodic table that separates metals from non-metals. 5. **Conclusion**: Therefore, the correct classification of the elements B, Si, and Ge is that they are metalloids. **Final Answer**: Boron, Silicon, and Germanium are metalloids. ---

Silicon is the second most abundant element (~27.2%) in the earth's after oxygen (45.5 %) Carbon. Silicon, germanium, tin and lead constitute the group 14 of the periodic table. Chemistry of silicon is distinctly different from that of carbon. For example, under standard conditions CO_(2) is a gas whereas SiO_(2) is a covalent solid.
