Is hydrogen always a nonmetal or can it be a metal? What is it usually treated as? Thanks.
Yes, hydrogen is a non-metallic element. It is located in group 1 of the periodic table, which contains all non-metals.
Hydrogen is a colorless, odorless, and highly flammable gas. It is a poor conductor of heat and electricity, and it can form covalent bonds with other non-metallic elements.
The metallic behavior of an element is characterized by its ability to lose electrons and form positive ions, whereas the non-metallic behavior is characterized by its tendency to gain electrons and form negative ions. Hydrogen, being a non-metal, has a high electronegativity and tends to gain electrons to form negative ions.
Yes, there are some cases where hydrogen can exhibit metallic behavior. For example, at extremely high pressures, hydrogen can behave as a metal and conduct electricity. Additionally, when combined with other metals, such as in the compound sodium hydride, hydrogen can act as a metallic element.
No, hydrogen cannot be classified as a metalloid. Metalloids have properties that fall in between those of metals and non-metals, and they are located along the zigzag line on the periodic table. Hydrogen, on the other hand, is clearly classified as a non-metal and is not located on the zigzag line.
