group 0 (or group 18 as it is called in the modern periodic table) or noble gases are all non metals.
the non-metallic character generally decreases down a group.

As you go down Group 0 (also known as the noble gases), both metals and nonmetals tend to become less reactive. The noble gases are already very stable and unreactive, and this reactivity decreases even further as you move down the group. Metals in Group 0, called alkali metals, also become more reactive as you go down the group, while nonmetals in Group 0, known as halogens, become less reactive.

Where are the metals and nonmetals located on the peridoic table?
The metals are located in the left going toward the right. The nonmetals are located in the right going down the periodic table.
Which group of nonmetals are most reactive?
The group of nonmetal of nonmetals on the periodic table that is the most reactive is the alkali metals
Why basic character of alkali metals increases down the group?
Basic character depends upon electron loosing tendency of an element which increases down the group,SO basic character of alkali metals increases down the group
How does reactivity change down the group of atoms?
Reactivity generally increases down a group of atoms. This is because as you move down the group, the atomic radius increases and the valence electrons become further from the nucleus. As a result, the valence electrons are less strongly attracted to the nucleus, making them more easily available for bond formation and chemical reactions.
Which trend decreases for metals down a group?
Melting Point
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
Where are the metals and nonmetals located on the peridoic table?
The metals are located in the left going toward the right. The nonmetals are located in the right going down the periodic table.
Where are metals located on the periodic chart?
The more left and the more down in the periodic table, you'll find the metals (except hydrogen). Only in the upper right corner (at fluorine) are the nonmetals. On the mid-diagonal in between both corners there is the greatest group containg the metalloids (half metals). But excluded from all this, is the 'noble gas'-group.
How does reactivity work with the elements going down the groups for metals and non metals?
Reactivity increases down the group for metals. It decreases down the group for non-metals.
Among the alkali metals how does the tendency to react with other substances change within a group?
The chemical reactivity increase down in the group.
Which group of nonmetals are most reactive?
The group of nonmetal of nonmetals on the periodic table that is the most reactive is the alkali metals
Which group of elements form cations?
what are true about cationA.Metals are not likely to form cations.B.Cations are always smaller than the neutral form of the element.C.Cation size decreases as you go down a group.D.All cations are larger than any anion.E.Cations cannot form in nature.
Why some metals are found in the group with nonmetals?
With the ecception of th ehalogens, group 17, the groups that have non-metals as the lightest groups 13, 14, 15, 16, the metallic character of the elements generally increaes as you go "down" the group, as the atomic number increases. As you go down a group the ionization potentials drop, it becomes progressivly easier for the electrons to be removed. This is one of the prerequisites for a metallic bond where the s and p electrons are "free to roam". the more obvious concluion is that the formation of cations gets easier which is characteristic of metals.
Are the halogens most reactive nonmetals or the least reactive nonmetals?
The Halogens are the most reactive non-metals. However, their reactivity decreases as you go down the group. Most reactive Fluorine>Chlorine>Bromine>Iodine>Astatine Least reactive. However, Astatine is not fully characterised because it is radio-active, and consequently is not found in open(school) labs.
Why basic character of alkali metals increases down the group?
Basic character depends upon electron loosing tendency of an element which increases down the group,SO basic character of alkali metals increases down the group
How does reactivity work with the elements when you go down the groups?
Down the group, reactivity decreases for non metals. It increases for metals.
How does reactivity change down the group of atoms?
Reactivity generally increases down a group of atoms. This is because as you move down the group, the atomic radius increases and the valence electrons become further from the nucleus. As a result, the valence electrons are less strongly attracted to the nucleus, making them more easily available for bond formation and chemical reactions.
