Predict reactivity of francium with cold water?
The reactivity of francium with water would be more reactive than most of the other alkali metals, because the lower down the column of alkali metals you go in the periodic table the more reactive the element becomes in cold water. Therefore, if francium was to react with cold water it would react by giving off an explosion.
What group would lithium be in on the periodic table?
They are in group one called the Alkali Metals.Those are alkali metals. They are the most reactive of all the metals, and they are in group 1 of the periodic table, all the way to the left.
Would a metal in the boron family or alkali metal be more reactive?
A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.
Which elements are as reactive as alkali metals?
Halogens: When reacting with halogens, these metals create metal halides. Halide refers to a compound that is one part halogen. These reactions would look similar to
What property of metals are reactivity?
It means metals that are highly reactive. It's one of the most self-evident pieces of terminology in all of chemistry. Perhaps you were trying to ask which metals are considered "highly reactive", which is a separate question, and one that to some extent depends on your definitions, but would certainly at minimum include all the alkali metals, maybe the alkaline earth metals, and possibly a few selected others (aluminium, for example... we don't usually think of aluminium as "highly reactive" because it immediately forms a thin transparent protective layer of aluminium oxide when exposed to air, but without that layer, it is indeed pretty reactive).
What is the most reactive group of metals?
in group 1, the first column on the left Edit: these would be the alkali metals.
What is the most reactive groups of metals in the periodic table?
the alkali metals are the most reactive... either cesium or francium would be the most reactive out of this group.

Where are the most reactive element found on the periodic table?
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.

In what family would you classify cesium?
Cesium is a reactive soft metal that has a "valency" of 1 and forms ionic compounds. It is in group 1, the alkali metals
What 4 alkali metals are the most reactive?
Alkali metals have increasing reactivity going down the group. Francium may not be considered as it is not a stable atom: it is radioactive. The next four are Cesium, Rubidium, Potassium and Sodium in decreasing reactivity order.

Is a coin an alkali?
No, a coin is not an alkali. It's a metal or metal alloy. Alkali metals are very reactive and coins are not made of them. These metals react with the water in air, so they are stored beneath a liquid they do not react with (like kerosene), or in a gas they will not react with (like an inert gas). Making coins out of alkali metals would give entirely new meanings to "depreciation" and the phrase "money burns a hole in my pocket."
