Sodium and manganese are both chemical elements with the following properties:
Sodium (atomic number 11) is a highly reactive, silvery-white metal that is highly reactive and prone to oxidation. It is a good conductor of heat and electricity, and it has a high melting and boiling point.
Manganese (atomic number 25) is a hard, brittle, gray-white metal that is similar to iron and steel in many ways. It is an essential trace element for humans and animals, and it is used in a wide range of industrial processes, including steelmaking and the production of glass, ceramics, and batteries.
Some other properties that both sodium and manganese have in common include:
They are both solid at room temperature.
They both have relatively low densities.
They are both found in nature as compounds rather than as pure elements.
They are both toxic in large amounts and can cause health problems if ingested or inhaled.
