Francium is the most reactive chemical element; unfortunately is extremely rare and currently not available for chemical experiments. Also is very radioactive.

What family is the element Rubidium in?
It is a metallic element in the alkali family
What are the names of group 1?
Group 1 is known as the 'Alkali Metals' They are in descending order of the group ; lithium, sodium, potassium rubidium, caesium, and francium. They become increasing reactive with water on descending the group , to the point of explosion. Francium is not found in the lab, because it is also radio-active. The Group 2 are known as the 'Alkali Earth Metals'. Because they are frequently found in rocks e.g. Calcium and magnesium as Calcium Carbonayte and magnesium carbonate.
List all of the alkali metals?
In order of reaction strength: Lithium Sodium Potassium Rubidium Cesium Francium Look in related links for a video demonstrating the reactions of different alkali metals mixed with water.
Why are Alkali metals so reactive?
Alkali Metals are group One elements and have one electron in their outer electron shell. In order to become stable they tend to lose an electron by reacting with something that needs an electron to become stable such as a group seven halogen. The Alkali Metal then become positive ions.This is because they only have on valance electron. This makes it easier to react with other elements and more often also.
Which choice has the element groups in the correct order from left to right on the periodic table?
Alkali metals, alkaline earth metals, transition metals
What family is the element Rubidium in?
It is a metallic element in the alkali family
What order of reactivity NOT activity are the metals Barium Lithium Radium and Sodium in?
The metals listed are all alkali metals or alkali-earth metals. The periodic trend for these groups is: as you move down the group/family, reactivity increases. The alkali metals will be more reactive than the respective alkali-earth metals.Sodium and lithium are alkali metals, so you can organize them first. Sodium is further down in the family than lithium, so we can say that sodium is the most reactive out of the group, followed by lithium. Then we have barium and radium left. Radium is slightly more reactive than barium due to its position, so it is third and barium is fourth.

What is the correct list of elemental families in order going from left to right?
Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases
Why are groups sometimes called families?
In chemistry, the vertical columns on the periodic table, are known as groups or families. The elements belonging to the same group or family have the same number of valence electrons and hence similar properties.

Alkali metals, alkaline earth metals, transition metals

What would alkali metal atoms need in order to end up with the same stable electron arrangements as the noble gas?
alkali metals need to loose one electron. alkali earth metals need to loose two
What is the most reactive group of elements in the periodic table?
Alkali Metals (group 1) because they only need to lose one electron in order to have a stable valence level of 8. As you go down the alkali metals group, the elements become more reactive. So Francium is the most reactive alkali metal. Also, Halogens, because they already have 7 electrons and only need to gain one in order to have a stable valence level of 8. As you go up the halogens group, the elements become more reactive. So Fluorine is the most reactive halogen. This is just a brief summary, if you want to know the reasons why this is I suggest you search about ionization energy, electron affinity, and electronegativity because these are all what make an element "reactive."
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.
