group 1, period 5. symbol Rb
These six elements are Li, Na, K, Rb, Cs and Fr.
Rubidium is an element and its chemical symbol on the periodic table is Rb [Atomic number:37]
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).
If you look at a periodic table and go to group one, and than the element with an atomic number of 37 it is Rb. The atomic number is the number of protons and electrons. Rb is Rubidium.
There is no R in the periodic table. There is Rb, Rf, Re, and Rn.
Rb is the symbol for the element, rubidium.
It stands for Rubidium
Rb has lower electronegativity than Na. Electronegativity decreases as you move down a group in the periodic table, so Rb, which is located below Na in the periodic table, has lower electronegativity.
Rubidium (Rb) is located in the 5th period of the periodic table.
In group 1, the far left column of the Periodic Table, which is Lithium (Li), Sodium (Na), Potassium (K), Rudibium (Rb).
group 1, period 5. symbol Rb
group 1 is Li, Na, K, Rb, Cs and Fr.
Li+,Na+,K+,Rb+,Cs+,Fr+
There are 18 groups and 7 periods in the modern periodic table.
These elements are Cs, Rb, K, La, Ac, Po, Tl.
Xe has a larger atomic radius than Rb because atomic radius generally increases from top to bottom within a group in the periodic table. Xe is located below Rb in the periodic table, so it has more electron shells, resulting in a larger atomic radius.
