Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
Does tin has a larger atomic size than iodine?
The empirically measured covalent radius of tin is 145 pm; for iodine this radius is 140 pm.
What two element are out of order in periodic table?
It might be Iodine and Tellurium because Tellurium has a larger atomic weight than Iodine but Iodine has more similar properties with Fluorine and Chlorine so Mendeleev placed them that way to make more sense but at that point the elements were aranged in order of atomic mass. Now the periodic table is in order of it's atomic number rather than it's atomic mass so it all fits nicely.
Why pottasium with atomic number 19 is more reactive than lithium with atomic number 3?
potasium has larger atomic radius so loses electrons more readily. All alkali metals are very reactive, but each one is slightly more reactive than the one directly above it in the periodic table. Tha larger the atomic radius the weaker the attractive force will be so the electrons farther from the nucleus are lost more easily during the reaction.
How does electron shielding explain why it is easier to remove an electron from rubidium than from lithium?
In rubidium, having a larger atomic radius, the attraction force between the atomic nucleus and and the electron from outermost shell is lower.
What element has larger atomic radius than rubidium?
nitrogen- .70 angstroms (oxygen- .66 angstroms)
Is the atomic radius for Ne higher for Li?
Lithium is significantly larger.
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
Does tin has a larger atomic size than iodine?
The empirically measured covalent radius of tin is 145 pm; for iodine this radius is 140 pm.
Which has the largest atomic radius li or be?
Lithium has a larger atomic radius than hydrogen.
Which atom is the smallest among lithium and fluorine?
Fluorine because it has a smaller atomic radius.

Is a rubidium larger or smaller than a neutral atom?
Rubidium is a neutral atom in its elemental form. The rubidium ion, found in rubidium compounds, is smaller than a neutral rubidium atom.
Why sodium is more reactive the lithum?
lithium is IA group element .As lithium is basic it should give its electron easily but it is not that effecient in this as sodium.As it has small radius and high nuclear attraction towards its electrons.but sodium has larger atomic radii than the lithium less nuclear attraction towards its electrons.thus sodium is more reactive than lithium.
Which has a larger atomic radius sodium or cesium?
No. Lithium and sodium are both from the same column of the periodic table and so have similar chemical properties. Lithium is atomic number 3 with a weight of 6.94. Sodium is much bigger and heavier with an atomic number of 11 and a weight of 22.99.
