Sodium, potassium and rubidium are in the first group of the Periodic Table.
Sodium is in the period 3.
Potassium is in the period 4.
Rubidium is in the period 5.
Rubidium (Rb) is located in the 5th period of the periodic table.
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.
Rb is found in the 5th period. It is in the s block.
I think you lost some formatting there. Na+ is isoelectronic with neon, if that's what you were trying to ask.
Rb is the symbol for the element, rubidium.
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.

Rubidium (Rb) is located in the 5th period of the periodic table.
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.
Rb is found in the 5th period. It is in the s block.
group 1 is Li, Na, K, Rb, Cs and Fr.
Group 1 Li, Na, K, Rb, Cs, Fr
Element Rb (Rubidium) has the lowest ionization energy among Rb, Na, C, and F. This is because as you move down a group on the periodic table, the ionization energy typically decreases due to the increase in atomic size. Rubidium is located below sodium (Na) in the same group, so it has a lower ionization energy.
The alkali metals are: Li, Na, K, Rb, Cs, Fr.
Elements in Group 1 include, Li, Na, K, Rb, Cs, Fr
Group 1, alkalis metals: Li, Na, K, Rb, Cs, Fr.
Rb (rubidium) is the largest element among K (potassium), Rb (rubidium), Na (sodium), and Li (lithium). This is because as you move down a group in the periodic table, the atomic size increases due to the addition of more electron shells.
