Thallium is a moderately reactive metal.
It corrodes easily in air with a blue-gray color that is similar to lead.
If it is kept in air for a long time, a large amount of thallium(I) oxide will build up.
It corrodes in the presence of water to make the hydroxide.
It burns with a greenish flame.
It reacts with most acids.
