Lithium is altogether a bigger element than hydrogen. Hydrogen is the smallest element, and lithium is listed later on the Periodic Table, so lithium's radius is just plain bigger than hydrogen.

∙ 11y agoPotassium and chlorine are in the fourth and the third period in the periodic table. Potassium forms a mono positive ion whereas chlorine forms a mono negative ion. After forming the ions, potassium has no electrons in the valence shell whereas chlorine has eight. Therefore these ions are iso electronic. Bu as the nucleus of potassium has more protons, it can attract the electrons more. Therefore the ionic radius of potassium is lesser than chlorine.

The atomic radius of bromine is lower.
What does this distance indicate about an atom of lithium?
You think probable to atomic radius.
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
Which element in each pair has atoms with a larger atomic radius selenium oxygen?
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
What has the smallest atomic radius out of hydrogen sodium and lithium?
Hydrogen has the smallest atomic radius - 25 pm.
Which atom is the smallest among lithium and fluorine?
Fluorine because it has a smaller atomic radius.
What is the atomic radius of lithium in angstroms?
2.05
