What else can I help you with?
What family is the element Rubidium in?
It is a metallic element in the alkali family
What is the order or reducing property of alkali metals?
The reducing property of alkali metals increases down the group. This is because as you move down the group, the outermost electron is further away from the nucleus, making it easier to lose and therefore easier to act as a reducing agent.
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
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.
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.

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

What is the most reactive group of elements in the periodic table?
The alkali metals, group 1 elements, are the most reactive group of elements in the periodic table. They readily lose their outermost electron to achieve a stable electron configuration, resulting in highly reactive behavior.
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.
What is the lightest of the alkali metals?
Lithium, sodium, potassium, in order of lighter to heavier
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.
If a metal reacts violently with water in which group is it most likely to be found?
Any of the group 1 metals, so lithium, sodium, potassium (you've probably seen these done at school), caesium and francium. That list is in order of reactivity from least to most. Though they are all pretty impressive!
