Question

State at leat five physical properties of metals

Answer 1

Five physical properties of metals are given as follows:

• Malleable - Metals are highly malleable hence they can be drawn into sheets. Gold $\left(\mathrm{Au}\right)$ is the most malleable metal.
• Ductile - Metals are highly ductile hence they can be drawn into wires. Gold $\left(\mathrm{Au}\right)$ is also the most ductile metal.
• Solid - Metals remains as solid at room temperature as the chemical bonding present between their constituent atoms is strong. An exception is mercury $\left(\mathrm{Hg}\right)$ which is liquid at room temperature.
• Hardness - Metals are generally hard because of the strong bond present between the constituent atoms which cannot be broken easily. Exception is sodium $\left(\mathrm{Na}\right)$ is a soft metal and can be cut with a knife.
• Lustrous - Metals are highly lustrous and when cut with a knife the cut piece appears shiny.
