Metalloid - Wikipedia
Metalloids are variously grouped with metals, regarded as nonmetals or treated as a sub-egory of nonmetals.  [n 12] Other authors have suggested that classifying some elements as metalloids "emphasizes that properties change gradually rather than abruptly as one moves across or down the periodic table".

Reaction with oxygen: When metal is treated with oxygen on heating they react together to give basic oxides. 4Na + O 2 → 2Na 2 O Reaction with Hydrogen: Metals like sodium, potassium, and calcium burn in hydrogen and forms corresponding halides. 2Na + H 2 → 2NaH (sodium hydride)
