What order of reactivity NOT activity are the metals Barium Lithium Radium and Sodium in?
TheAnsweringAsker
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 atom has the largest size in period 5?
Look for the highest numbered atom in the group: radium. Also barium has an empirical radius similar to the radius of radium: 215 pm.
Which element is more reactive lithium or barium?
Definitely lithium. Lithium is a Group I alkali metal, while Beryllium is a Group II alkaline earth metal and are on the same period. Group I Alkali metals are generally more reactive as they only need to lose one electron to have a complete outer shell.
The most reactive metal in group 1 of the periodic table?
Probable lanthanum.The chemical reactivity (and electronegativity) are very similar for lanthanoids. This explain the difficulties of identification and separation.
List all of the alkali earth metals?
Beryllium, magnesium, calcium, strontium, barium, and radium.
What elements are in group 2a?
Beryllium, magnesium, calcium, strontium, barium and radium are the group IIA elements.
What are some reactivity?
lithium, sodium, potassium, rubidium, cesium, francium, beryllium, magnesium, calcium, strontium, barium, radium
Where is radium on the reactivity scale?
Radium is the "heaviest known alkaline earth; it's chemical properties mostly resemble those of barium." "Like other alkaline earth metals, radium reacts violently with water to form radium hydroxide." This puts radium with Cs, Rb, K, Na, Li, Ba, Sr and Ca on the reactivity scale; in other words, highly reactive.Please see the links.
What are the members of the alkali family?
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium, Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
What atom has the largest size in period 5?
Look for the highest numbered atom in the group: radium. Also barium has an empirical radius similar to the radius of radium: 215 pm.
Do alkaline earth metals react with water?
The reactivity is increasing from beryllium to barium.
Why is radium found in uranium ores but not in barium ores?
Radium is a decay product of uranium.
Which element is more reactive lithium or barium?
Definitely lithium. Lithium is a Group I alkali metal, while Beryllium is a Group II alkaline earth metal and are on the same period. Group I Alkali metals are generally more reactive as they only need to lose one electron to have a complete outer shell.
How many Alkaline earth metals are there on the Periodic Table of Elements?
Six elements are there. And they are: beryllium, magnesium, calcium, strontium, barium, radium
What are the other heaviset member of group 2 other than radium?
Barium is the heaviest element in the group 2 after Radium. Chemical symbol for barium is Ba. Atomic number of it is 56.
Does beryllium or barium have a bigger atomic radius?
Radium has a much larger atomic radius than beryllium.
What members are in the alkaline earth family?
Group 2 elements or alkaline earth metals are beryllium, magnesium, calcium, strontium, barium and radium
What is heavier Beryllium magnesium calcium strontium barium or radium?
The maximum density in this list: radium with 5,50 g/cm3.
