Physical state at 20°C and 1013 hPa:
solid
Form:
crystalline
Colour:
The reference describes the substance as follows.

The colour of tin is white, with a slightly bluish tinge. When it is compared with nickel, the latter metal is brown in comparison ; and with chromium [tin] is definitely blue. Tin is whiter than silver or zinc. The metal has a brilliant luster and when highly polished has a high light reflectivity. The luster depends to a large extent upon the temperature at which the metal is poured when cast.
Substance type:
element
Conclusions:
Tin is described in the review as a white metal with a blue tinge.
Executive summary:

Tin is described in the review as a white metal with a blue tinge.

Description of key information

From publically available data and observations made in a GLP physico-chemical properties study, the general consensus of the appearance/physical state/colour of tin is a grey-white odourless metal that is solid room temperature.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
solid

Additional information

Tin is a grey-white odourless metal which is found to be solid at room temperature.
