Is francium the largest and most reactive metal?
Francium is the largest alkali metal, but it is not the largest or most reactive metal overall. It is highly reactive due to its position on the periodic table, which means it will react violently with water and air. However, there are other metals that are more reactive than francium, such as cesium and potassium.
Which element is the most reacitve?
It turns out that fluorine is the most reactive element. It is at the top of the Group 17 elements, the halogens. And they are, as a group, the most reactive group on the periodic chart.
Which element has 55 protons?
Barium (Ba)
Is Cs a element or a compound?
Cs is a chemical element with the atomic number 55 and the symbol Cs. It is known as caesium in the British spelling and is a member of the alkali metal group.
Reactivity of s-block element?
S-block elements are highly reactive due to the presence of one or two electrons in their outermost electron shell. These elements readily donate or lose these electrons to achieve a stable electron configuration, resulting in strong reactivity with other elements. The reactivity of s-block elements generally increases down the group.
The element Cs Ba and Lu appear from left to right in. Six of the periodic table elements which is most reactive?
Cs (Caesium) is the most reactive!!!!
The elements cesium Cs Barium Ba and lutetium Lu appear from left to right in Period 6 of the periodic table Among these elements the most reactive is?
The most reactive element among cesium (Cs), barium (Ba), and lutetium (Lu) is cesium (Cs). Cesium is located at the far left of Period 6 in the periodic table and has a single valence electron, which makes it highly reactive.
What element is most active as you go down the peiodic table Cs or K?
As you go down the periodic table, elements become less reactive. Therefore, potassium (K) is more reactive than cesium (Cs) because cesium is located further down the group compared to potassium.
Which element would you expect to be the most reactive in group 1 and group 2?
In Group 1, cesium (Cs) is expected to be the most reactive element, as reactivity increases down the group due to the increasing atomic radius and the decreasing ionization energy. In Group 2, barium (Ba) is typically the most reactive, as reactivity also increases down this group for similar reasons—larger atomic size and lower ionization energy. Both cesium and barium readily lose their outermost electrons, making them highly reactive.
What is the element the only stable isotope of a particular alkali metal that has 78 neutrons?
Ba and Cs
Which element shows least active chemical behavior Cs Rb Na?
Cesium (Cs) shows the least active chemical behavior among these elements. It is located at the bottom of Group 1 in the periodic table and has the largest atomic radius, making it the most reactive metal in Group 1. Rb (Rubidium) and Na (Sodium) are more reactive than Cs.
Is francium the largest and most reactive metal?

What Group 1A elements is the most reactive cs Li K Na?
K
What element has the atomic mass of 56?
The element with an atomic number of 51 is Sb - Antimony; atomic weight = 121.75.
What element in the flame test was excited using a Bunsen burner?
Examples: Na, K, Li, Cs, Ba, Ca, etc.
What element is located in period 6 on the periodic table?
The elements in period 6 are: Cs , Ba, Pb , Bi , Po,At and Rn
