Yes, rubidium (Rb) is more reactive than lithium (Li), potassium (K), sodium (Na), and cesium (Cs). In the alkali metal group, reactivity increases as you move down the Periodic Table due to the increasing atomic size and the decreasing ionization energy, which makes it easier for the atoms to lose their outermost electron. Thus, Rb, being below K and Na, is more reactive than all of them. However, cesium (Cs) is even more reactive than rubidium.
What else can I help you with?
Name an alkali metal that is more reactive than K Na or Li Name an alkali metal that is less reactive?
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
How many valence electrons are found in alkali metals Li Na K Rb Cs and Fr?
Alkali metals such as Li, Na, K, Rb, Cs, and Fr each have 1 valence electron. This is because they have a single electron in their outermost electron shell, making them highly reactive and likely to lose that electron to achieve a stable electron configuration.
The most reactive metal among the following is?
The most reactive metals of the periodic table are those that belong to alkali group. Among this group, the more electrons contain each atom of each element, the more reactive it is. This is why Francium is the most reactive of alkali metals.
Which elements are the alkali metals?
The metals in the far left column of the periodic table are the alkali metals. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
What family of elements in the period table contains the most reactive metals?
The most reactive metals are the alkali metals in group 1a.
Name an alkali metal that is more reactive than K Na or Li Name an alkali metal that is less reactive?
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
What Group 1A elements is the most reactive cs Li K Na?
K
Is Li more chemically reactive than Na?
No, sodium (Na) is more chemically reactive than lithium (Li) because sodium has an outer electron configuration that makes it more likely to lose an electron and form compounds.
What is the more reactive metal Cs or Na?
Cesium (Cs) is more reactive than sodium (Na) because it is located lower in the alkali metal group on the periodic table. This means that cesium has a larger atomic radius and lower ionization energy, making it more likely to lose an electron and react with other substances.
How many valence electrons are found in alkali metals Li Na K Rb Cs and Fr?
Alkali metals such as Li, Na, K, Rb, Cs, and Fr each have 1 valence electron. This is because they have a single electron in their outermost electron shell, making them highly reactive and likely to lose that electron to achieve a stable electron configuration.
Which element shows least active chemical behavior Cs Rb Na?
Cesium (Cs) shows the least active chemical behavior among these elements. It is located at the bottom of Group 1 in the periodic table and has the largest atomic radius, making it the most reactive metal in Group 1. Rb (Rubidium) and Na (Sodium) are more reactive than Cs.
Which is more reactive na or li why?
Sodium (Na) is more reactive than lithium (Li) because sodium has a smaller atomic size and lower ionization energy, making it easier for sodium to lose an electron and form a more stable configuration compared to lithium. This results in sodium being more prone to reacting with other elements and compounds.
The most reactive metal among the following is?
The most reactive metals of the periodic table are those that belong to alkali group. Among this group, the more electrons contain each atom of each element, the more reactive it is. This is why Francium is the most reactive of alkali metals.
Are all the alkali metals metallic?
H Li Na K Rb Cs Fr
What are group 1 elements?
The alkali metals are: Li, Na, K, Rb, Cs, Fr.
What is Group 1 on the periodic table?
group 1 is Li, Na, K, Rb, Cs and Fr.
What are the atomic symbols for alkai metals?
Li Na K Rb Cs Fr (hope this is help)
