Choose the element that is largest Li Na Rb K?
Rb (Rubidium) is the largest element among Li, Na, Rb, and K as you move down the same group or in the same period from left to right on the periodic table.
What is the most reactive among Li Na K Rb?
Lithium (Li) is the most reactive among Li, Na, K, and Rb due to its small atomic size and low ionization energy, making it easier for it to lose its outer electron and form compounds. Sodium (Na) would be next in reactivity, followed by potassium (K) and then rubidium (Rb).
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.
In what ways are the electron configurations of H Li Na K Rb and Cs similar?
The electron configurations of H, Li, Na, K, Rb, and Cs are similar in that they all have one valence electron in their outermost energy level. These elements belong to the alkali metal group in the periodic table and tend to exhibit similar chemical properties due to their outermost electron configuration.
Which of these elements is the smallest element sodium potassium rubidium or cesium?
Of the Group 1 elements stated (Na, K, Rb, Cs), Caesium is the largest as it is the furthest down the group, and Sodium is the smallest of those as it is furthest up the group.
Choose the element that is largest Li Na Rb K?
Rb (Rubidium) is the largest element among Li, Na, Rb, and K as you move down the same group or in the same period from left to right on the periodic table.
What element is the largest out of Li Rb Na and K?
Rubidium (Rb) is the largest element among lithium (Li), sodium (Na), and potassium (K). This is because, as you move down the alkali metal group in the periodic table, the atomic size increases due to the addition of electron shells. Therefore, Rb, being the heaviest and furthest down the group, has the largest atomic radius.
Which grouping of circles when considered in order from the top to the bottom best represent the relative size of the atom of Li Na K and Rb respectively?
Rb > K > Na > Li. The order based on atomic size is Rb > K > Na > Li. Therefore, the size of the circles should reflect this order from largest to smallest.
What element has the smallest first ionization energy of Li Na Rb and K?
Rb
What is the smallest to largest Li Li Rb Cs?
Smallest to largest is going down the group 1. I.e. Li is smallest<Rb<Cs
An element in group 1 of the periodic table?
Elements in Group 1 include, Li, Na, K, Rb, Cs, Fr
Which element has the smallest first ionization energy Na K Rb Li?
The element with the smallest first ionization energy is Francium, as it is located in Group 1 of the periodic table and has the largest atomic size. Among the elements listed, lithium (Li) would have the smallest first ionization energy as it is closer to the upper right of the periodic table compared to sodium (Na), potassium (K), and rubidium (Rb).
When Na forms an ion it loses its outer electron to become Na what element does Na resemble?
I think you lost some formatting there. Na+ is isoelectronic with neon, if that's what you were trying to ask.
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 symbols in group V of period 1 to 6?
H Li Na K Rb Cs
