Why are alkali metals and halogens the most reactive families?
Alexandra810
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.

This is becasue all elements want to have a full valence shell of electrons. When alkali metals loose an electron they become positive Cations.

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 halogens.
Which periodic table famiy is the most reactive?
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
What is the most reactive family of nonmetals and metals?
The most reactive nonmetals are in group 17 (halogens). The most reactive metals are in group 1 (alkali metals).
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 are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
What chemical family is most reactive?
The most reactive groups are alkali metals and halogens.
The Family of what is the most reactive group of metals in the periodic table?
The Alkali metals are the most reactive group of metals in the periodic table. Of these Francium is the most reactive metal of all.
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 halogens.
Which periodic table famiy is the most reactive?
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
What is the most reactive family of nonmetals and metals?
The most reactive nonmetals are in group 17 (halogens). The most reactive metals are in group 1 (alkali metals).
Which category is the most reactive on the periodic table?
Alkali metals and halogens.
What groups are the very reactive elements from?
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
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
What are the families in periodic table?
alkali metals, alkali earth, transition metals, non metals, halogens, noble gases
What are examples of high reactivity?
Very reactive elements are alkali metals and halogens.
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.
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.
