has-large-font-size\">\n<li><strong>Lustre<\/strong>: Metals have a shiny appearance (metallic lustre).<\/li>\n\n\n\n<li><strong>Malleability<\/strong>: Metals can be hammered into thin sheets (e.g., aluminum foil).<\/li>\n\n\n\n<li><strong>Ductility<\/strong>: Metals can be drawn into thin wires (e.g., copper wires).<\/li>\n\n\n\n<li><strong>Conductivity<\/strong>: Metals are good conductors of heat and electricity (e.g., silver, copper).<\/li>\n\n\n\n<li><strong>Sonority<\/strong>: Metals produce a ringing sound when struck (sonorous).<\/li>\n\n\n\n<li><strong>Hardness<\/strong>: Metals are generally hard (exceptions: sodium and potassium are soft).<\/li>\n\n\n\n<li><strong>High Melting and Boiling Points<\/strong>: Most metals have high melting and boiling points (e.g., iron, tungsten).<\/li>\n\n\n\n<li><strong>Density<\/strong>: Metals are generally dense (heavy for their size).<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity

Non-Metals<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Non-Lustrous<\/strong>: Non-metals are dull in appearance (exceptions: iodine is lustrous).<\/li>\n\n\n\n<li><strong>Non-Malleable<\/strong>: Non-metals are brittle and break when hammered.<\/li>\n\n\n\n<li><strong>Non-Ductile<\/strong>: Non-metals cannot be drawn into wires.<\/li>\n\n\n\n<li><strong>Poor Conductors<\/strong>: Non-metals are poor conductors of heat and electricity (exceptions: graphite conducts electricity).<\/li>\n\n\n\n<li><strong>Non-Sonorous<\/strong>: Non-metals do not produce a ringing sound.<\/li>\n\n\n\n<li><strong>Softness<\/strong>: Most non-metals are soft (exceptions: diamond is the hardest natural substance).<\/li>\n\n\n\n<li><strong>Low Melting and Boiling Points<\/strong>: Non-metals generally have low melting and boiling points.<\/li>\n\n\n\n<li><strong>Low
