Beside above, why is fluorine the most reactive nonmetal? 4. It depends on the number of electrons in their outer energy level. The non-metal and oxygen gas (O 2) are the reactants in this type of reaction, and a non-metal oxide is the product. 1st - most reactive. (reactive nonmetal!) Without a list of options I belive the safest answer would just be noble gases. You did not include the list but F is fluorine. (b) phosphorus. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H3O+) in aqueous solution. Fluorine is the most reactive non-metal because it is the most electronegative of all of the non-metal elements of the periodic table. If a matchstick is brought near the mouth of the tube containing the product of the reaction then we hear a pop sound. The most reactive nonmetals reside in the upper right portion of the periodic table. Under conditions of high pressure, hydrogen is predicted to behave as an alkali metal. 4 years ago. The electronic configuration of fluorine is [He]2s²2p⁵. Some nonmetals are very reactive, whereas others are not reactive at all. Reaction with oxygen: Non-metals react with oxygen to form acidic oxides. 0. Nonmetals are distributed into two groups reflecting their relative tendency to create chemical compounds specifically reactive nonmetals and noble gases. The oxides of non-metals are acidic or neutral in nature. The reaction between non-metals and bases is a very complex one. Due to its strong electro negativity & small size, Fluorine has a strong tendency to accept electrons from other atoms or ions.
