You need to look up the measurements. The interactive Periodic Table of the Royal Society of Chemistry can be found here:http://www.rsc.org/periodic-table/?gclid=CjwKEAjw2MOhBRCq-Nr87_j-lDASJAAl4FNhssVbsyCT_UjwmmrpVjUngib6tHybHy88YrC1gH_1shoCZDzw_wcB
Click on the element you are interested in to find data about it. Radii get bigger as you go down the table, and smaller as you go to the right so we'd expect rubidium to be larger.
What else can I help you with?
What happens to the radii of rubidium and strontium?
The radius of strontium is smaller than the radius of rubidium.
Which has a larger radius arsenic or phosphorus?
Carbon has a larger atomic radius than nitrogen. The radii of these compounds are 67pm and 56pm, respectively. This occurs because the electrons in nitrogen are more attracted to the nucleus than electrons in carbon.
What is the atomic radius of selenium if germanium's is 122 pm and arsenic's is 120 pm?
The atomic radius of selenium can be estimated to be approximately between 116 pm and 118 pm based on the trends in atomic radii going down a group in the periodic table. This is because atomic radius generally increases as you move down a group, so selenium's atomic radius would be smaller than arsenic's and germanium's.
How can you find out the atomic radii?
Look for a reference chart in a book or online. Look for a Periodic Table of the Elements that has the atomic radii on it.
Define atomic radii?
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
What is vanadium's atomic radii?
vanadiums atomic weight is 50 AMUs
Smallest to largest atomic radius PotassiumMagnesiumCalciumRubidium?
Rubidium has the largest atomic radius, followed by potassium, calcium, and then magnesium. This trend is due to an increase in the number of electron shells and shielding effects as you move down the periodic table from potassium to rubidium.
Why are the ionic radii of metallic elements smaller than the atomic radii of the same elements?
The ionic radii of metallic elements is smaller than its atomic radii, because the ion has less electrons. This gives it a smaller electron cloud and makes the atom smaller.
Why are van der waals radii larger than atomic raddii?
Van der Waals radii are larger than atomic radii because they include the space occupied by the electron clouds around the atom, which are not considered in atomic radii. Van der Waals radii are used to estimate the effective size of atoms when they are close to each other and experience van der Waals forces.
Where are atoms with the largest and smallest atomic radii found?
The atoms with the largest atomic radii are found in the lower right side of the periodic table. Smallest atoms are found in the higher left part of the periodic table. He has the smallest atomic radii.
Graph the atomic radii for the first 20 elements?
I'm unable to graph atomic radii in this text-based format. However, you can find data on atomic radii for the first 20 elements in a periodic table resource or chemistry textbook. Atomic radii generally decrease across a period from left to right and increase down a group from top to bottom.
