Where are the most active nonmetals located on the periodic table


The most active nonmetals belong to the halogen family, which sits to the left of the noble gases on the right side of the periodic table. The halogens are so reactive that they are never found in nature by themselves. The elements fluorine, chlorine, bromine, iodine and astatine make up the halogen family.

Group 7


Elements in the group 7 of the periodic table are known as the halogens. They are the most active/reactive nonmetals because they have just one electron to receive in order to achieve there octet configuration. They react easily with elements in group 1 (in the same proportion) since group 1 elements have just one electron in there outermost shell. Halogens easily form acids with hydrogen by sharing the only electron hydrogen has with its own valence electron via covalent bonding. They however undergo ionic bonding with the remaining members of group 1. They also react with metals in group 2, 3 and 4 in different proportion.

Option (d) is the correct answer.


Metals are the substances that have more number of electrons. In order to attain stability, metals lose electrons and thus becomes positively charged.

A metal with less number of valence electrons will be more reactive because it will readily lose its valence electrons to become stable.

For example, atomic number of potassium is 19 with electronic distribution is 2, 8, 8, 1. Potassium is a group I element. So, to become stable it will lose its 1 extra electron readily.

Therefore, we can conclude that the most reactive metals on the periodic table are placed on to the far left.

I’m looking at it

halogens are the most reactive nonmetals.

on the periodic table, alkali metals are the most reactive ones and are found in the first group of elements on the left side of the table. Alkali metals such as  lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr) are reactive because they have extra electron which they are trying really hard to get rid of. Once they get rid of this electron, these elements have a full octet.

option B = lower left of the periodic table


The most reactive metals are located at the bottom left corner of periodic table. These metals are reactive in the sense that they can react with water very easily.

Examples include lithium, sodium potassium. As we move down the group in this column metallic character increase. Their atomic radius also increases and electron can easily donated. which means metals became more reactive.

These metals can also react very easily with O2 in atmosphere that's way these are stored in inert atmosphere. The most reactive metal in periodic table is francium.

The correct answer is: They are found in the upper right portion of the periodic table, before the noble gases.


The most reactive nonmetals elements of the periodic table are the halogens (group 17). This group is formed by 5 different elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At); from which fluorine is the most reactive out of the 5.

These elements are the most reactive nonmetals because they have one space in their valence electron shells.

The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.

Do you mean to question where are the most reactive metals on the periodic table? In case, that would be group 1; the Alkali Metals.
