krypton is a nonmetal
Hydrogen...
Cl is Chlorine, is an element... but it exist as Cl2(g) as its most stable form in room temperature Cl - element (halogen) Cl2 - compound
A non-metal element needs to gain one or more electrons to form an anion. This allows the non-metal to achieve a stable electron configuration, usually by filling its valence shell. The addition of electrons gives the non-metal a negative charge, turning it into an anion.
Fluroine is the most reactive non-metal.
Fluorine is the most reactive non-metal element. It readily gains an electron to achieve a stable electron configuration, making it highly reactive.
eon is stable in nature. It is an inert element.
Neptunium (Np) is a metal. It belongs to f block elements or actinides.
Fluorine is a non metal element. Atomic number of it is 9.
argon is a non- metal.It is a colourless odourless gas
krypton is a nonmetal
Hydrogen...
Hydrogen is not considered a metal. It is a non-metal and is the first element on the periodic table. In its pure form, hydrogen exists as a diatomic gas and is the most abundant element in the universe.

Carbon is an element. It is a non metal
Oxygen (although hydrogen is the most abundant element in the universe)
Cl is Chlorine, is an element... but it exist as Cl2(g) as its most stable form in room temperature Cl - element (halogen) Cl2 - compound
