in general they become more reactive.
The far left - alkali metals and the far right (not noble metals but next - the Halogens.
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
The metals on the left side of the periodic table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
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.
the number of elements in the atom The group the element is in on the periodic table (how many valence electrons it has). Metals increase in reactivity from right to left on the periodic table and non metals increase in reactivity from left to right, with the exception of group group 18, which is not reactive, and Hydrogen, which is very reactive.
Reactivity decreases from left to right.Alkali metals on the left are most reactive.While noble gases on the right are least reactive.
Reactivity increases the farther down you go in the Periodic Table.
The reactivity increases with increasing numbers of electron shells (energy levels).
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
The chemical reactivity of alkali metals increase when the atomic number increase.
The metals become more reactive as you move down and left.
Reactivity of non-metals increases as you move from left to right on the periodic table, or as group number increases. The most reactive non-metals are found in group 17.
The far left - alkali metals and the far right (not noble metals but next - the Halogens.

Maybe there is no pattern...no it fals
