Why are the alkali metals and the halogens among the reactive elements an the periodic table?

alkali metals have one valence electron and halogens have 7. since elements always want to have a full outer shell, these two types of elements react easily with each other to form a full outer shell of 8 electrons.

∙ 9y agoAlkali metals only have one valence electron and halogens only need one electron to complete their outer valence shell. This means that they will be extremely reactive with all other elements.

∙ 15y agoAlkaline metals are reactive because they contain one electron in their outer shell. Halogens are reactive because they contain seven electrons in their outer shell. The closer the number is to one or seven, the more reactive the element is. Elements with eight electrons in their outer shell show little or no reactivity.

∙ 13y agoThe basic reason is that the alkali metals have only 1 electron to lose to become stable and the halogens have only 1 electron to gain to become stable. The vast majority of the other elements have more than 1 electron to lose or gain. This takes more energy and makes them less reactive.

∙ 13y agobecause to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)

The two most reactive groups of elements in the periodic table are the alkali metals and the what?
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
Where on the periodic table are element most likely to react with other elements which direction?
The most reactive elements are alkali metals and halogens.
What are the reactive elements on the periodic table?
The reactive elements on the periodic table are typically found in groups 1 and 2 (for example, alkali metals like sodium and potassium) and groups 16 and 17 (for example, halogens like chlorine and fluorine). These elements are reactive because they readily form compounds with other elements to achieve a stable electron configuration.
Where are the alkali metals and the halogens located on the periodic table?
The alkali metals are located in Group 1 of the periodic table, while the halogens are located in Group 17. Alkali metals are highly reactive metals that include elements like lithium, sodium, and potassium, while the halogens are a group of highly reactive nonmetals that include elements like fluorine, chlorine, and iodine.
Which periodic table famiy is the most reactive?
The alkali metals family, which includes elements like lithium and sodium, is the most reactive group on the periodic table. These elements readily give up their outermost electron to form a +1 oxidation state, leading to high reactivity with other elements.
The two most reactive groups of elements in the periodic table are the alkali metals and the what?
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
What groups are the very reactive elements from?
The very reactive elements are typically found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table. Alkali metals tend to react violently with water, while halogens are known for their high reactivity and tendency to form salts with metals.
Where on the periodic table are element most likely to react with other elements which direction?
The most reactive elements are alkali metals and halogens.
Why are the alkali metals and Halogens among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
Why alkali metals and the halogens among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
What are the most reactive elements on the periodic table?
The alkali metals and the halogens are the most reactive groups and among them, francium and fluorine are the most reactive, especially with each other.
Which category is the most reactive on the periodic table?
Alkali metals and halogens.
What are two most reactive groups in the periodic table?
The alkali metals (Group 1) and the halogens (Group 17) are the most reactive groups in the periodic table. Alkali metals are highly reactive due to their low ionization energies, while halogens are reactive because of their strong tendency to gain an electron to achieve a full outer shell.
What are the 2 most reactive group?
The alkali metals (Group 1) and the halogens (Group 17) are among the most reactive groups on the periodic table. Alkali metals readily react with water, while halogens are highly reactive nonmetals that easily form compounds with other elements.
What are the reactive elements on the periodic table?
The reactive elements on the periodic table are typically found in groups 1 and 2 (for example, alkali metals like sodium and potassium) and groups 16 and 17 (for example, halogens like chlorine and fluorine). These elements are reactive because they readily form compounds with other elements to achieve a stable electron configuration.
Where are the alkali metals and the halogens located on the periodic table?
The alkali metals are located in Group 1 of the periodic table, while the halogens are located in Group 17. Alkali metals are highly reactive metals that include elements like lithium, sodium, and potassium, while the halogens are a group of highly reactive nonmetals that include elements like fluorine, chlorine, and iodine.
What group of elements on the periodic table is most reactive?
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
