No, oxygen cannot act like a metal. Oxygen is a gaseous element found in the Earth's atmosphere and is not considered a metal. Metals are characterized by their ability to conduct heat and electricity, their lustrous appearance, and their ability to be deformed without breaking.
Oxygen, on the other hand, is a nonmetal. Nonmetals generally have properties that are opposite to those of metals. They are typically poor conductors of heat and electricity, tend to be brittle in solid form, and often have lower melting and boiling points compared to metals.
However, under certain extreme conditions, such as high pressure, oxygen can exhibit some metallic properties. When subjected to extremely high pressures, oxygen molecules can undergo a phase transition and form a solid metallic state. In this state, known as "solid oxygen," oxygen atoms can behave like a metal, conducting electricity and exhibiting metallic luster. However, solid oxygen is not naturally occurring under normal conditions and is only achieved under controlled laboratory conditions at very high pressures.
