Metals are generally hard in nature and exist in solid-state. But metals like sodium and potassium are soft metals that can easily be cut down. Mercury is also an exception as it exists in a liquid state at room temperature.
Metals have high density. But Lithium is an alkali metal with a low density of 0.53.
Metals like gold, silver, platinum and copper do not release hydrogen gas when reacted with acids.
All metals are sonorous in nature except mercury. This means it does not produce sound when struck on a hard surface.
All metals are malleable except mercury.
Metals are solid substances that are insoluble in water but sodium and potassium are the metals that react violently with water to form soluble hydroxides.
