How chemically active are halogens?
Very, tho reactivity decreases down the group
What is the most reactive halogen?
the halogens decrease in reactivity as you move down the group, so i guess that the least reactive would be Astatine. Hope this helps =)
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
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 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.
What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
Does halogens reactivity decreese as you mov down the group?
Nope.
How chemically active are halogens?
Very, tho reactivity decreases down the group
What can you say about reactivity of the halogens as you go down the group from fluorine to astatine?
Reactivity decreases. In other words, fluorine is the most reactive of the halogens while astatine is the lease reactive. This is because the ability to attract electrons(electronegativity) decreases as you go down the group.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
What halogen is most likely to react?
The reactivity of halogens decreases down the group, which means Fluorine is the most reactive halogens as it is the most electronegative elements among the halogens, and also the Periodic Table.
Why does reactivity of the halogens decrease down the group?
As it go down the group, the distance between the nucleus (+ve) and the last electron (-ve) becomes smaller No: BIGGER.Therefore the electrons are held in the atom very tightly more loosely by a strong weakening force from the nucleus.So, it is said as the reactivityDEcreases down the group of NON-metals which gain stronger their electrons andINcreases down the group of metals which loose those electrons.
How reactive are halogens?
In the periodic table, the reactivity of the halogens that are found in Group 17 decreases as you go down the column of elements in this group. The first element of the group is fluorine, and it has the highest reactivity. The other elements in this group are chlorine, bromine, iodine, and astatine.
How do you tell the reactiveness of a non metal on the periodic table?
The periodicity of nonmetals is that reactivity increases from left to right across a period, through group 17, the halogens. As you move down a group, reactivity decreases. Fluorine is the most reactive element.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What element is most reactive in the group 7a?
flourine, reactivity goes down group 7Florine (F)
Alkali metal reactivity?
the reactivity increases as you go down the group
