Reactivity, unlike other periodic trends, does not increase or decrease going across a period or up and down a group. Instead, the least reactive elements are found in the center of the d block and in group eight (the noble gases). Reactivity then increases moving to the left and right ends of the table. The most reactive elements are found in the upper right hand corner of the p block and the lower left hand corner of the s block.

∙ 12y agoWell, depends. For the metals, eg. period 3 there's Potassium, Calcium and Aluminium. Reactivity decreases since while potassium needs to lose one electron to achieve stability, aluminum needs to lose three.
For non-metals, on the other hand, taking Carbon, Nitrogen, Oxygen and Fluorine (excluding noble gases) the opposite is true. While carbon needs energy to form 4 covalent bonds, or to gain four electrons, fluorine only needs to gain one electron or form one covalent bond. Thus reactivity increases along the period for non metals.

Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
How do the reactivity of the alkali metals change in group 1?
because of the power of each metal it goes up in reaction.
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 element in 1a group is more reactivity?
fransium
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.
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.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
What happens to reactivity of nonmetals within a group from the top of the group to the bottom?
they go from smaller to the largest
How does the reactivity of halogens change as you go down group 7?
dno
How does the reactivity of each group of metals change across the table from the right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
What do elements within a group have a similar number of?
Chemical elements that are in the same group within the periodic table have the same numbers of electrons in the outermost shell. This gives them similar reactivity.
How does the reactivity of each group of metal of change across the table from left to right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
How does the reactivity of each group of metals change across the table from right to left?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
How does the reactivity of each group of metals change across the table left to right?
Reactivity of metals decreases from left to right in the specific period of theperiodic table.
Is reactivity a chemical change?
Reactivity is not a change; it is a chemical property.
Alkali metal reactivity?
the reactivity increases as you go down the group
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
