Cesium and francium are the most reactive and lithium is the least.
Because the reactivity of alkali metals increases going down the group.
Down the group: atomic and ionic radii and density increase while melting and boiling points decrease. Therefore it is easy for them to lose the one electron on the outer orbital. So it is very reactive.
What else can I help you with?
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.
Why do halogens form compounds with alkali metals?
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
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.
What is the most reactive family of nonmetals and metals?
The halogens are the most reactive family of nonmetals, as they have a strong tendency to gain an electron to achieve a full outer shell. Among metals, the alkali metals are the most reactive due to their low ionization energy and strong tendency to lose an electron to achieve a stable electron configuration.
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.
What is three families from the periodic table?
Three families from the periodic table are the alkali metals (group 1), the halogens (group 17), and the noble gases (group 18). Alkali metals are highly reactive, halogens are nonmetals that are also reactive, and noble gases are inert gases with low reactivity.
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.
Which category is the most reactive on the periodic table?
Alkali metals and 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.
What is the correct list of elemental families in order going from left to right?
Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases
The Family of what is the most reactive group of metals in the periodic table?
The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.
What are the families in periodic table?
alkali metals, alkali earth, transition metals, non metals, halogens, noble gases
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 examples of high reactivity?
Very reactive elements are alkali metals and halogens.
Why do halogens form compounds with alkali metals?
Because halogens form negative ions, alkali metals form positive ions; both are reactive elements and an electrostatic attraction exist.
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.
What is the most reactive family of nonmetals and metals?
The halogens are the most reactive family of nonmetals, as they have a strong tendency to gain an electron to achieve a full outer shell. Among metals, the alkali metals are the most reactive due to their low ionization energy and strong tendency to lose an electron to achieve a stable electron configuration.
