Which element has the largest atomic radius TI or as?

Which elements have the largest atomic radius?

Francium has the largest, Helium has the lowest. Atomic radius increases as you go to the left and downward due to the attraction of electrons and the nucleus in an atom.

Which has largest radius?

Atomic radii are measured in picometers (one picometer is equal to one trillionth of a meter). Hydrogen (H) has the smallest average atomic radius at about 25 pm, while caesium (Cs) has the largest average radius at about 260 pm.

Which element has a larger atomic radius than sulfur?

Cadmium has larger atomic radius than sulfur.

Which element has the largest atomic radius Na or CS?

(A) Comparison of Atomic and Ionic Radius of Group 1 (IA, alkali metals) Elements

Is Br or Br bigger?

Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.

What has the smallest atomic radius?

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.

Which has a larger radius Na or Na 1?

So p/e ratio is 1 and Na+ ion nucleus has eleven positive (p) charge and ten negative charge (e). … As is known from the chemistry course, when the element loses electron (turn into cation, with positive charge), the atom radius is getting low, so obviously Na+ is smaller than Na.

Which has a larger radius F or F?

F has a larger radius than F− because an additional electron causes greater repulsion in F.

Which has the largest radius Co3+ Mn3+ fe3+ Cr3+?

Fe 3+ has highest radii because by going left to right in the periodic table , the size get decreased so .. Fe 3+ >Co3+ >Cr3+ >Mn3+ .

How do you find atomic radius?

Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.

Which has a larger atomic radius S or S2?

(ii) Explain why the radius of the S2- ion is larger than the radius of the S atom. The nuclear charge is the same for both species, but the eight valence electrons in the sulfide ion experience a greater amount of electron-electron repulsion than do the six valence electrons in the neutral sulfur atom.

What is the atomic radius of sulfur?

180 pm

Which atom is larger Li or O?

So, they both have n=2, or 2 shells, but O has more protons in the nucleus pulling the electrons closer. Thus, Li would have a larger atomic radius.

Why is atomic radius of K greater 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.

Which ion has the largest atomic radius?

1 Answer. Ernest Z. K+ has the largest radius.
