What else can I help you with?
What is the second most reactive metal?
The 2nd most reactive is Cesium after Francium. If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.
What are the three weak alkali?
Lithium, Sodium and Potassium are the 'weaker' alkali metals. Rubidium, Caesium and Francium are the most volatile. Francium is only found in micron-grams and is highly radioactive.
What is the difference between rubidium and seslium?
If you mean "What is the difference between rubidium and cesium?" then Rubidium and cesium are two different elements.They have similar properties but cesium is denser and has a higher atomic mass.Cesium also reacts more vigorously with water and air.
Is rubidium in any household objects?
No, rubidium is not found in household objects.
Is francium a good conductor of heat?
The estimated thermal conductivity of francium is 15 W/m.K.
Which element has the smallest atomic radius rubidium cesium and francium?
Francium has the largest atomic radius among rubidium, cesium, and francium, as atomic radius generally increases down a group in the periodic table.
What are the three most reactive metals?
Francium, caesium, rubidium
What other elements are in the same group as francium?
Alkali metals are: lithium, sodium, potassium, rubidium, caesium and francium.
Rubidium cesium and francium all have one valence electron Which element has the smallest atomic radius?
Francium has the smallest atomic radius among rubidium, cesium, and francium because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of Group 1, which means it has the largest nuclear charge pulling the valence electron closer to the nucleus, resulting in a smaller atomic radius.
Elements in group one?
Lithium, Sodium, Potassium, Rubidium, Cesium, & Francium
What are all the alkaline metals?
Lithium, Sodium, Potassium, Rubidium, Cesium, Francium.
Does rubidium cesium and francium have the same atomic radius?
The empirical atomic radius of rubidium is 235 pm.The empirical atomic radius of caesium is 260 pm.The empirical atomic radius of francium is supposed to be approx. 260 pm.
Alkalis discovered since 1860?
Caesium: 1860 Rubidium: 1861 Francium: 1939
List all the alkali metals?
Lithium Sodium Potassium Rubidium Cesium Francium
What are the seven groups of alkaline?
Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
What elementare in the alkali metal family?
Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr) are elements in the alkali metal family. They are highly reactive, soft metals that readily lose their outer electron to become positively charged ions.
What are the similarities of potassium and francium?
Lithium, sodium potassium, caesium, rubidium and francium are all alkali metals; consequently they share many chemical and physical properties.
