Which elements would have properties most similar to cesium (Cs)?
Rb
What is the oxidation number of Rb?
The oxidation number of Rb is 1.
Is Rb a metal or non metal?
Rb (rubidium) is a metal.
How many electrons do Rb have?
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.
Which of the following has the smallest radius is K plus Rb Rb plus K?
K+
What are the resulting spectator ions when aqueous solutions of Rb2O and CaCl2 are added together?
When Rb2O and CaCl2 are added together, the resulting spectator ions are Cl^- and Rb^+ ions. This is because the Rb^+ ions from Rb2O do not participate in the reaction, and the Cl^- ions from CaCl2 similarly remain unchanged. The reaction forms CaO and RbCl as the products.
Which elements reacts rapidly when dropped in water?
Rubidium (Rb)
What period is the element rb in the periodic table?
Rb is the symbol for the element, rubidium.
Chlorine ionically bonds to which element Ni Cu Ga or Rb?
Chlorine typically ionic bonds with metals, so out of the options provided (Ni, Cu, Ga, Rb), it would most likely form an ionic bond with Rb (Rubidium), due to its lower ionization energy.
Which elements would have properties most similar to cesium (Cs)?
Rb
What does the RB stand for on your ray bans?
Um - that would be Ray Ban!
What does Contemporary RB mean?
RB as it is at this time
What is the value of a RB 1979 nickel?
RB ???
What is an alkali metal that would melt on a very hot day?
Rubidium (Rb)
Rank from most to fewest valence electrons- Sb In Rb Xe?
Sb has 5 valence electrons, In has 3, Rb has 1 valence electron and Xe has 8. So in ranking, it would be, Xe, Sb, In, Rb.
What is the chemical formula for rubidium nitrate?
These are the ions and their charges: Rb+1 N-3The charges have to add up to zero, so two +1 Rb ions were added to cancel out the -3 charge of N: Rb+1 Rb+1 Rb+1 N-3Simplify: Rb3N
What has the author RB Wood written?
R.B Wood has written: 'Water quality in an Ulster nature reserve'
