What atomic radius is larger Rb or Sr?
Rb
Which has larger atomic size F or F ion?
Ionization energy increase across a period and decreases down a group, therefore the the element with the greater ionization energy would be found in the top right of the periodic table. In this instance fluorine, F would have the greater ionization energy.
Which has the smallest radius K Rb K Rb?
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
What group of elements have members of the smallest atomic radii for a given period?
Noble gases have the smallest atomic radius.

What atomic radius is larger Rb or Sr?
Rb
What is the atomic radius of Rb?
Rubidium has an atomic radius of 248 picometers.

Which has the smallest radius K Rb K Rb?
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
Why does Rb have a greater atomic radius than K?
A potassium atom has 19 protons and 19 electrons, plus 20-22 neutrons. A rubidium atom has 37 protons and 37 electrons, plus 46-50 neutrons and so is bigger.
How many neurons are in an atom of 82 Rb?
There are 45 neutrons in an atom of rubidium. There are also 37 protons and the atomic mass is 82.
What group of elements have members of the smallest atomic radii for a given period?
Noble gases have the smallest atomic radius.
What is the atomic weight of Rb?
85.4678 is the atomic weight of Rb.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H

Which element is the largest K Rb Na Li?
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
Rank these elements in terms of increasing atomic radius?
In terms of atomic radius, the sequence would be oxygen, carbon (both period 2), magnesium (period 3), rubidium (period 4), and cesium (period 5). Note that order by periods is not absolute: in each period, the elements toward the far left side have the largest radii. For example, the radius for lithium in period 2 is larger than almost all of the elements in periods 3 and 4. *Numerically, the elements O, C, Mg, Rb, and Cs have respective radii of about 60, 70, 150, 235, and 260 picometers.
