In the alkali metals and the alkaline earth metals (groups IA and IIA on the Periodic Table), all increase in reactivity as one goes down the columns. These elements react by loaning out electrons, and it is easier to loan out an electron if the valence band where that lone electron (group IA) or two (group IIA) hangs out is farther from the nucleus and is screened by other (more) electrons in lower bands. The elements farther down the columns are more reactive because they can more easily loan out electrons. Just as an aside, one might expect that the elements that borrow electrons might be better able to do that if there was less electron screening, right? And that would suggest that the elements higher in the columns of the groups that are seriously interested in borrowing electrons (think group VIIA) would be more reactive than the lower ones, wouldn't it? Maybe that's why fluorine is called the hungry wolf of the periodic table.
Yes, as you move from left to right across the periodic table, the metallic reactivity of an element decreases.
yes, metallic character increases as you move down, and also as you move from right to left
The most reactive metals are on the left of the periodic table.the first group starting with hydrogen is very reactive with air so they have to keep them in oil.
No, metals become less reactive as you move from left to right across the periodic table.
Yes. Elements are more likely to recieve electrons during a reaction if they are farther to the right on the periodic table.
No. The non-metallic property generally decreases down a group in the periodic table.
Yes. Down the group reactivity increases as the size gets larger and ionisation energy decreases.
Down the group, reactivity increases.
All metals are reactive, and there are 91 different metals on the periodic table.
the most reactive (non-metals) group in the periodic table is GROUP 17+they are all reactive
The Alkali metals are the most reactive group of metals in the periodic table. Of these Francium is the most reactive metal of all.
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
Sodium, aluminum, and magnesium are metals. For metals, reactivity decreases as you go from left to right across the periodic table. The least reactive of those three is therefore aluminum.
They don't
They become less reactive.
in the Periodic Table it is the most reactive metals!
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
All metals are reactive, and there are 91 different metals on the periodic table.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
the most reactive (non-metals) group in the periodic table is GROUP 17+they are all reactive
No the most reactive metals are in the first group on the periodic table. They get more reactive as you go down a group
The metals become more reactive as you move down and left.
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
Most reactive metals are in the lower left corner.
