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.
What else can I help you with?
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.

How many cubic inches in a 18 inch diameter cylinder 54 inches tall?
To calculate the volume of a cylinder, we use the formula V = πr^2h, where r is the radius and h is the height. The radius of a cylinder with an 18-inch diameter is 9 inches. So, the volume of the cylinder is V = π * 9^2 * 54 = 13,627.76 cubic inches.
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'
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 17 plus 37?
17 + 37 = 54
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.
What is the radius if the circumference is 54?
Well, darling, if the circumference is 54, then we can use the formula C = 2πr to find the radius. Just plug in the circumference (54) and solve for r. So, 54 = 2πr, divide by 2π, and you'll find that the radius is 27/π or approximately 8.59. Voilà!
What is the area of a circle if the radius is 5?
54
How many protons in Chlorine-37?
