easily gain electrons
all are non metals
metals on left, non-metals on right, some others in middle.
Atoms of non-metals usually gain or share electrons when they react with other atoms.
metals, non metals, metaloids
It depends what you consider 'active'. Out of the non metals the most reactive is usually Fluorine as it's electon arrangement causes it to react well with anything with a spare electon.
It's carbon Or perhaps Florine.
The most active non metals are the halogens, located in group XVII. They are the most active non-metals because they only need 1 electron to make their outer shell complete.
Non metals
The most active nonmetals are located in group 17. They are the halogens.
In the upper right hand corner reflecting high electrovegativity.
easily gain electrons
Metals, non metals and metaloids (which have some of the properties of both metals and non metals).
They are in between the metals and non metals
