Fluorine has the most non metallic qualities.
Hydrogen...
krypton is a nonmetal
Chlorine is not a metalloid. It is a non metal.
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.
Fluorine is a non metal element. Atomic number of it is 9.
Neptunium (Np) is a metal. It belongs to f block elements or actinides.
argon is a non- metal.It is a colourless odourless gas
Hydrogen...
krypton is a nonmetal
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.
