The reactivity of an element is significantly influenced by the number of electrons in its group shell. Elements with a nearly complete group shell tend to be more reactive as they seek to either gain or lose electrons to achieve a stable electronic configuration. This is why metals, which often have one or two electrons in their group shell, readily donate them, while nonmetals, with five or six electrons in their group shell, tend to gain electrons to complete their shell.

Moreover, fiberglass stair treads require minimal maintenance. Unlike metal or wooden treads that can rust, warp, or decay over time, these treads maintain their integrity and appearance with only occasional cleaning. Their resistance to chemicals and UV rays ensures they retain their color and structural stability even in harsh environments Their resistance to chemicals and UV rays ensures they retain their color and structural stability even in harsh environments Their resistance to chemicals and UV rays ensures they retain their color and structural stability even in harsh environments Their resistance to chemicals and UV rays ensures they retain their color and structural stability even in harsh environmentsfiberglass stair tread.
