Rubidium's atomic radius is greater than xenon's because the trend for atomic radius is that it decreases left to right across a period (even though atomic number increases, and generally speaking, Atomic Mass does as well.) This is a result of the attraction between the protons in the nucleus and the valence electrons, which are all in the same energy level for isoperiodic elements.

Which element on the periodic table has 54 electrons?
Elements on the periodic table are arranged according to the number of protons in their nucleus, also known as their atomic number.54th element on the periodic table is Xenon.
What city is at 54 degrees south and 37 degrees west?
atlantic ocean
What element 54 electrons with a -2 charge?
BARIUM
Which element has 77 protons in its nucleus?
Xenon. Take the atomic mass of 131 and subtract it's protons 54, to get 77 neutrons.
What atomic mass does a calcium have?
Iron is a meta element. Atomic mass of it is 54. Atomic number of it is 26.
What is the sum of 54 and 37?
54 + 37 = 91
What is the radius of a circle with a 54 feet circumference?
radius = 54/(2*pi)
37 out of 54 is equivalent to what percent?
37/54 = 68.'518'% recurring '518'
Is Xenon element 54?
Yes - Xenon is element 54
What is 1998 divided by 37?
54
What 2 prime numbers make the sum 54?
17 and 37. 17+37=54
HOW TO Calculate increase from 54 to 74?
To get to 74, 54 has to increase by 20. 20 is 37% of 54, so that's a 37% increase.
What is diameter of a circle with the radius of 54 inches?
The diameter is essentially twice the radius, so therefore a circle with a radius of 54 inches has a diameter of 108 inches.
What is the mean of 36 37 37 76 84?
54.
What is 17 plus 37?
17 + 37 = 54
What is the radius if the circumference is 54?
Radius of a circle = circumference/(2*pi)
What is the diameter of a circle if the radius is 27 cm?
When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.
