What are the most active groups in the periodic table?
Generally the most reactive elements in the periodic table are found in the first two (left-most) columns: the alkali metal and alkali earths.
Least reactive to most reactive elements Lithium potassium Rubidium.?
rubidium
The elements cesium Barium and lutetium appear from left to right in Period 6 of the periodic table Among these elements the most reactive is?
Barium, since lutetium is also a metal. (At the next-to-rightmost column of this period is iodine, which may be as reactive as barium but is a nonmetal.)
What category of elements are the most reactive?
The alkali metals group.
Which element is most reactive potassium or iron or alumimum?
Among the elements listed in the question, potassium, by a large margin, is most reactive.
What gas is the most reactive of all elements?
Francium is the most reactive metal and fluorine the most reactive nonmetal.
Would a metal in Group 13 be more or less reactive that a metal in Group 1?
less reactive.beacuse group-1 elements are the most reactive elements.
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.
What are the most reactive elements in the group of akali metals?
Alkali metals are the elements in the 1st group. In the 1st group,the reactivity of the elements increase down the group. Cs is the most reactive alkali metal.
Why is lithium the most reactant element?
I believe that Fluorine is the most reactive of the elements. Lithium may be the most reactive metal, but don't forget potassium.
What metal is the most reactive metal?
Fluorine is the most reactive non-metal.
What is the most reactive non-metal?
The most reactive non-metal is fluorine. It is often nicknamed the 'Tyrannosaurus Rex' of the elements because of its reactivity. NB . Oxygen ,which we breath, is also a very reactive element. If it wasn't so reactive we would probably die.
What is the most reactive metal and nonmetal group in the periodic table?
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
What is the gas that metal reacts with?
Fluorine gas is one of the most reactive elements that exist and it will react with most metals.
Most reactive non metal?
The most reactive nonmetals are the Halogens, found in group 17. These elements tend to have 7 electrons in their outermost energy level (valence electrons). Since they only need one more electron to stabilize, they react easily to form a negative ion.
What are the most active groups in the periodic table?
Generally the most reactive elements in the periodic table are found in the first two (left-most) columns: the alkali metal and alkali earths.
How do you find out what metal is the most reactive?
Metals which can easily loose electron are most reactive. They are present in group-1.
