Step 1:I'll solve this problem step by step, focusing on the characteristics of nonmetals.
Step 2:: Understand the Definition of Nonmetals
Nonmetals are elements located on the right side of the periodic table (primarily in the upper right), characterized by distinct physical and chemical properties that differ from metals.
Step 3:: Analyze Each Property
- $$\therefore$$ This is FALSE
A. Malleable - Nonmetals are NOT malleable - Metals can be hammered into thin sheets - Nonmetals tend to break or shatter when stressed B. Brittle - Nonmetals are typically brittle - They fracture easily under stress C. Solid at Room Temperature - Not all nonmetals are solid at room temperature - Some nonmetals like bromine and chlorine are liquids/gases D. Low Density - Nonmetals generally have lower density compared to metals E. Electrical Insulator - Nonmetals do not conduct electricity well - They resist electrical current F. Thermal Conductor - Nonmetals are POOR heat conductors - They are thermal INSULATORS, not conductors
Final Answer
B. Brittle D. Low density E. Electrical insulator
