What is the periodic trend for reactivity of metals?

Answer 1

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.

Answer 2

The reactivity of metals generally decreases as you move from left to right across the periodic table. This trend is due to the decreasing tendency of metals to lose electrons and form positive ions. Conversely, as you move down a group, reactivity tends to increase since it becomes easier for metals to lose electrons and form positive ions.

Answer 3

they are higly reactive in nature and react with water to form stron hydroxides

Answer 4

Down the group, reactivity of metals increases

Answer 5

For group I, the reactivity increases down the group. Hence, of the alkali metals, lithium is least reactive (though already quite reactive) which francium is the most reactive.

Answer 6

on the leftb further down more reactivr on the right further up more reactive trancition metals are scattered bottom all the sameish

Answer 7

Down a group, the reactivity and metallic character increases. Across a period, the metallic character decreases.

Answer 8

The reactivity increase down in the group.

Answer 9

The reactivity increases as it go's down the group
