Which is larger Li or F?
In your case, lithium has an atomic number equal to 3 and fluorine an atomic number equal to 9 . So fluorine has more protons in its nucleus. Keep this in mind. … As a result, the atomic size of fluorine will be smaller than that of lithium, or, in other words, lithium will have larger atomic radius than fluorine.
Which is bigger Li or NE?
Lithium has a larger atomic radius than Neon. This because the nuclear charge of Li is less compared to Ne.Li has atomic number 3 i.e 3 protons and Neon has atomic number 10 i.e 10 protons . Li doesnot pull its electrons towards its nucleus like Neon does it. lithium has the largest atomic radius.
Which element has the largest radius Na or CS?
(A) Comparison of Atomic and Ionic Radius of Group 1 (IA, alkali metals) Elements
| Element | Symbol of Atom | Ionic Radius 4 (pm) |
|---|---|---|
| sodium | Na | 102 |
| potassium | K | 138 |
| rubidium | Rb | 149 |
| cesium | Cs | 170 |
Which atom has a larger atomic radius C or F?
Comparing carbon (C) with an atomic number of 6 and fluorine (F) with an atomic number of 9, we can tell that, based on atomic radius trends, a carbon atom will have a larger radius than a fluorine atom since the three additional protons the fluorine has will pull its electrons closer to the nucleus and shrink the …
Is Cl or Br bigger?
As Br is smaller than Cl; therefore, Br- have a smaller ionization energy than Cl-. In short, since the outermost electron in bromine is farther from the nucleus than the outermost electron in chloride, it takes less energy to remove the outermost electron in bromide.
Which is smaller Li or F?
Answer. Fluorine is in the same period as lithium but to the right of lithium so it’s smaller which means Li is larger in size than F.
Which atom is biggest in size?
As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

Which atom is bigger Li or K?
K has two shells (n=4 vs n=2) more than Li, so it would be much larger. the electronic structure of atoms: principle quantum number, effective nuclear charge, etc.) C will have the slightly larger radius because it has one less proton and thus, a lower effective nuclear charge.
Why is the decrease in size between Li and Be?
In sodium and magnesium, the space closer to the nucleus is already very negatively charged, repelling the outershell electrons from getting much closer. But in berylium there aren’t any electrons to interfere with orbital size decreasing. So, large difference is observed in Li and Be compared to Na and Mg.
Which has largest radius?
Since the atomic radius decreases in a period but increases down the group so Sr of group II and period V is largest in size.
Is K larger than K+?
When at neutral, the potassium ion in the form of K has an electronic configuration of: … The K+ ion has its outermost electrons on the third energy level now and is size is smaller than that of K ion. Hence, K is larger than K+.
What has the smallest atomic radius?
Explanation: Helium has the smallest atomic radius. This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus.
Why is K bigger than Br?
Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.
Why does lithium have the largest atomic radius?
The effective nuclear charge is simply a measure of the net positive charge that affects the outermost electrons in an atom. In lithium’s case, the outermost electron is being screened from the nucleus by two core electrons. … That is why lithium has a larger atomic radius than beryllium.
Which ion has largest radius?
1 Answer. Ernest Z. K+ has the largest radius.
