What family is the element Rubidium in?
Rubidium is in the alkali metal family on the periodic table. It belongs to Group 1 and has similar properties to other alkali metals like sodium and potassium.
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?
The correct order of element groups from left to right on the periodic table is alkali metals, alkaline earth metals, transition metals, and then nonmetals and metalloids.
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?
The correct order of elemental families from left to right is alkali metals, alkaline earth metals, transition metals, metalloids, nonmetals, halogens, and noble gases.
Which choice has the element groups in the correct order from left to right on the periodic table?
The correct order of element groups from left to right on the periodic table is alkali metals, alkaline earth metals, transition metals, and then nonmetals and metalloids.

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 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 order of reactivity in these metals from least reactive to most reactive is: Barium, Radium, Sodium, Lithium. This is based on their tendency to lose electrons and form positive ions in chemical reactions. Barium and Radium are less reactive compared to Sodium and Lithium due to having a larger atomic size and higher electron shielding, making it harder for them to lose electrons.
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!
