The reactivity is increasing, from left to right - for example halogens.

What happens to non metals across the periodic table?
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.
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 the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What happens to the atomic radius as you go down the metals What happens to the reactivity?
Examples for the groups I an II of the periodic table:- the atomic radius grows from top to bottom- the electronegativity descends from top to bottom
What periodic trends of reactivity occur with the alkali metals?
Reactivity increases the farther down you go in the Periodic Table.
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.

What is the periodic trend for reactivity of metals?
Metals Period - reactivity decreases as you go from left to right across a period.Group - reactivity increases as you go down a group Why? The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity.Non-metals Period - reactivity increases as you go from the left to the right across a period.Group - reactivity decreases as you go down the group. Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron.
How does reactivity of elements change across the periodic table?
this is called periodicity, the chemical properties of elements as you go across a period. The reactivity would be very great at first, especially if you are only crossing main group elements, and then would become less reactive, then very reactive again, and then one group over they would be completely inert
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.
Alkali metal reactivity?
the reactivity increases as you go down the group
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.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What happens as you move down the family on a periodic table the reactivity?
the reactivity of metals increases as you go down a group in the periodic table. also elements in the same group have similar chemical properties because they have the same electronic configuration,i.e.they have the same arrangement of electrons
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.
