The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactive nonmetals. This is because they all have one empty space in their valence electron shells. Send Your Questions to Experts.
Invalid OTP! Here is the reactivity series including carbon and hydrogen:. Note that zinc and iron can be displaced from their oxides using carbon but not using hydrogen. However, copper can be extracted using carbon or hydrogen. The reactivity series In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. For example: A good way to remember the order of a reactivity series of metals is to use the first letter of each one to make up a silly sentence.
The tables show how the elements react with water and dilute acids: Element Reaction with water Potassium Violently Sodium Very quickly Lithium Quickly Calcium More slowly Element Reaction with dilute acids Calcium Very quickly Magnesium Quickly Zinc More slowly Iron More slowly than zinc Copper Very slowly Silver Barely reacts Gold Does not react Note that aluminium can be difficult to place in the correct position in the reactivity series during these experiments.
The most reactive element is fluorine, the first element in the halogen group. The most reactive metal is francium, the last alkali metal and most expensive element. The least reactive elements are the noble gases. Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements. The most reactive nonmetal is fluorine, F. The trend in reactivity in the nonmetals is the opposite of the trend in the metals.
In the nonmetals, reactivity increases as you move up a group, and to the left. In the metals , reactivity increases down a group and to the right. All of the halogens are nonmetals. Halogens are reactive because they want to obtain that last electron to fill their outer level. Fluorine is the smallest atom of the halogen elements.
It also has the strongest ability to attract electrons from other elements, making it the most reactive of the halogens. Some nonmetals are very reactive , whereas others are not reactive at all. It depends on the number of electrons in their outer energy level.
Reactive nonmetals tend to gain electrons. This explains why they cannot conduct electricity, which is a flow of electrons. Halogens are highly reactive , and they can be harmful or lethal to biological organisms in sufficient quantities. This reactivity is due to high electronegativity and high effective nuclear charge.
The most reactive nonmetals are located in Group a 1 c 17 b 2 d 18 Which is the most active or reactive nonmetal? Asked By: Marjatta Rettenberger Last Updated: 7th January, , The elements toward the bottom left corner of the periodic table are the, Davy's name for the element prevailed.
