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.

What is the order of reactivity of alkaline earth metals?
The order of reactivity of alkaline earth metals decreases down the group. This means that the reactivity decreases as you go from beryllium to radium. Beryllium is the least reactive, while radium is the most reactive.
Scientific words that start with r?
radium, radon, reaction, redox, reactivity
How will radium react with oxygen?
Radium will react with oxygen to form radium oxide (RaO) or radium peroxide (RaO2), depending on the conditions. These compounds are highly unstable and radioactive. Due to the high reactivity of radium, such reactions should be avoided as they can lead to hazardous situations.
What are some science words that begin with the letter R?
radium radon reaction reactivity redox
Where is platinum on the reactivity scale?
Right at the bottom.
What is radiums reactivity?
Radium react with halogens (F, Cl, Br, I), oxygen, nitrogen, water, etc. Radium is a very reactive alkaline earth metal (the Pauling electronegativity is 0,9).
What are some reactivity?
lithium, sodium, potassium, rubidium, cesium, francium, beryllium, magnesium, calcium, strontium, barium, radium
What is Reactivity of radium?
Radium is a highly reactive element that readily forms compounds with other elements, especially oxygen. It is known to react violently with water, releasing radium hydroxide and hydrogen gas. Due to its high reactivity, radium is always found in nature in compounds, never in its pure form.
What is the chemical reactivity of xenon?
It is chemically inert. Its electronegativity, on the Pauling scale is 2.60
What is the reactivity of promethium?
The electronegativity of promethium on the Pauling scale is 1,13; it is a reavtive metal.
What hardness is radium?
Radium has a hardness of around 1.5-2.5 on the Mohs scale, which is relatively soft compared to many other minerals.
What is the colour and rating scale for explosive reactivity of a material in the hazard class?
Yellow 3
