Physical Properties of Metal, Non-Metal and Metalloids

On the periodic table, metals are located on the left side and in the center, occupying the vast majority of the table.

Non-metals are located on the upper right side of the periodic table, with the exception of hydrogen, which is on the top left.

Metalloids are located along the stair-step line that separates metals from non-metals on the periodic table.

Malleability is the physical property of a substance that allows it to be hammered or rolled into thin sheets without breaking.

Luster is the physical property that describes how light reflects off the surface of a material, often described as shiny or dull.

Conductivity is the physical property that measures the ability of a material to allow heat or electricity to pass through it.

Volume is defined as the amount of three-dimensional space an object occupies. Mass refers to the amount of matter, while capacity and conductivity describe different physical properties.

Volume is measured in cubic units for solids, such as cubic centimeters (cm^3). Milliliters (mL) are typically used for liquid volume, and cm is a unit of length.

Metalloids have properties intermediate between metals and non-metals, which allows them to act as semi-conductors. Metals are generally conductors, and non-metals are generally insulators.

Non-metals are typically brittle, dull, and poor conductors (insulators). Being metallic is a characteristic property of metals, not non-metals.

Metals are characterized by being malleable, ductile, and good conductors. Brittleness is a property associated with non-metals or metalloids, not metals.

Metalloids possess electrical conductivity properties that fall between those of metals (conductors) and non-metals (insulators), making them semi-conductors.

Ductility is the physical property of a material that allows it to be drawn out into a thin wire. Malleability refers to the ability to be hammered into thin sheets.

Density is defined as mass per unit volume. A substance is denser if it has more mass packed into the same amount of space.

Malleability is the ability to be shaped or hammered without breaking. Brittle materials shatter or break when force is applied, making it the opposite of malleable.

Magnetic materials are those that are attracted to magnets. This is a specific physical property of certain metals like iron, nickel, and cobalt.

Since 1 mL is equivalent to 1 cm^3, 600 mL of water and 600 cm^3 of air represent the same volume. The other options compare units that do not equate to the same volume.

Physical properties are characteristics of matter that can be observed or measured without changing the substance's chemical identity. Density, luster, conductivity, and malleability fit this definition.

Density is calculated as mass divided by volume. Here, 25 g / 5 mL = 5 g/mL.

Density is calculated as mass divided by volume. Here, 27 g / 27 cm^3 = 1 g/cm^3.

The standard formula for density is mass (M) divided by volume (V), expressed as D = M/V.

An object will float in water if its density is less than the density of water (1 g/mL). Diet soda has a density of 0.945 g/mL, which is less than 1 g/mL.

Volume is the measure of the amount of space an object occupies. Mass is the amount of matter, and weight is the force of gravity on that mass.
