Is RG part of Group 11?
The short-lived transactinide roentgenium (Rg) (which, with a half-life of 3.6 seconds, is hardly good material for making coins) is also a member of Group 11. They are all relatively inert, corrosion-resistant metals which have been used for minting coins, hence their name.

So, Cesium is the most reactive element in group IA.
What does 11 mean in sodium?
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).
What does the number 11 stand for in the sodium block?
Each atom of atomic number 11 has 11 protons, which define it as sodium. The symbol for sodium is Na. The symbol comes from the Latin word natrium, which was an old word for salt.
