Rank the nonmetals in each set from most reactive (1) to least reactive (3). neon: selenium: fluorine

The periodic trend of reactivity depends on whether the elements are metals or nonmetals. For metals, reactivity increases down a group and from right to left across a period. Nonmetals do the opposite. For nonmetals, reactivity increases up a group and from left to right across a period. Therefore, the rank is as follows:

Fluorine

Selenium

Neon

Hope this answers the question. Have a nice day.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
