The alkali metals need to lose just one electron in order to obtain a stable electron arrangement, and the halogens need to gain just one electron in order to obtain a stable electron arrangement, so they are both very close to stability and therefore react very readily. Elements which need to either lose or gain a larger number of electrons have a harder time doing so, because the stability of a full outer shell is countered by the instability that results from having too much of a net electric charge. If an element needs to gain more than one electron in order to have a full outer shell, the first electron is relatively easy, but that atom then has a negative charge which repells other electrons event though it still needs more electrons to fill its outer shell.
What else can I help you with?
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.
What are the most reactive families on the periodic table and why are they the most reactive?
The alkali metals Lithium, Sodium, Potassium, Rubidium cesium and Francium is the most reactive group of metals. They are this way because they only need to lose one electron to gain a stable octet which is very favorable energetically. The most reactive group of non-metals is the halogens, Fluorine, Chlorine, Bromine, Iodine and Astatine. These are the exact opposite. They are extremely reactive because they only need to gain one electron to gain a stable octet which is again, highly energetically favorable.
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 Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
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 examples of high reactivity?
Very reactive elements are alkali metals and halogens.
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.
What groups is the most reactive alkaline earth or alkali or halogens or noble gases?
I think alkali is the most reactive one.
What reginon is very reactive metals found in the periodic table found in?
Very reactive metals are found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table.
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)
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.
Which category is the most reactive on the periodic table?
Alkali metals and halogens.
Which group of metals do halogens usually bond with offer an explanation?
For example halogens easily react with alkali metals because both are very reactive; compounds are with ionic bonds.
Which groups of elements are very reactive?
The alkali metals (Group 1) and the halogens (Group 17) are known to be very reactive elements. Alkali metals react vigorously with water, while halogens are highly reactive nonmetals that readily form compounds with other elements.
What are the most reactive families on the periodic table and why are they the most reactive?
The alkali metals Lithium, Sodium, Potassium, Rubidium cesium and Francium is the most reactive group of metals. They are this way because they only need to lose one electron to gain a stable octet which is very favorable energetically. The most reactive group of non-metals is the halogens, Fluorine, Chlorine, Bromine, Iodine and Astatine. These are the exact opposite. They are extremely reactive because they only need to gain one electron to gain a stable octet which is again, highly energetically favorable.
What elements on the table are most reactive why?
Sodium, Potassium, and other alkali metals are very reactive due to the low ionization enthalpy. Flourine, Chlorine and other halogens are very reactive due to the high negative electron gain enthalpy.
