Reactivity of metals decreases from left to right in the specific period of theperiodic table.
the reactivity increases as you go down the group
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.
Th reactivity of alkali metals increases from the top of Group 1A to the bottom
No, right to left.
The reactivity of alkali metals increases as you move down Group 1 from lithium to francium. This trend is due to the decreasing ionization energy, which makes it easier for the alkali metals to lose their outermost electron and become more reactive.
To put all six metals in order of reactivity, you can immerse each metal strip in a series of different metal salt solutions with increasing reactivity. Then observe and record the reactions at each stage to determine the relative reactivity of each metal. By comparing the results, you can establish the order of reactivity for all six metals.
As you move down the alkali metal group on the periodic table, chemical reactivity increases. This is because the outermost electron in alkali metals is easier to lose as you go down the group, resulting in more reactive behavior with water and air. Lithium is the least reactive alkali metal, while cesium is the most reactive.
If the question means REACTIVITY.. well..no, it decreases across and increses downwards..
Please check the associated link on the first group metals. It shows the reactivity of pure sodium and other group 1 elements
The cheap metal r ing from a vendor is more than gold in reactivity
True. Generally, the reactivity of metal elements increases as you move from left to right across the periodic table. This is because as you move towards the right, the elements have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
Potassium is a metal, characterized by its shiny appearance, high electrical conductivity, and reactivity with water to produce hydrogen gas. It belongs to the alkali metal group in the periodic table.
