Which Atom Has The Largest Atomic Radius S Or O?

Which group has the smallest atomic radius?

HeliumHelium 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.

Atomic radius decreases as you move across a period from left to right and decreases as you move up a group from bottom to top..

Which has largest atomic radius?

franciumAtomic radii vary in a predictable way across the periodic table. 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 is larger k or k+?

The cation of K+ is formed when K loses this outermost single electron to attain “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 is the atomic radius of SI?

111 pmSilicon/Atomic radius

Why does the atomic radius decrease as electrons are added to a shell?

Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.

Which is the highest metallic character?

cesiumThe natural element with the highest metallic character is cesium, which is found directly above francium on the periodic table.

What element has the largest atomic radius in Group 18?

radonThus radon has largest atomic radius.

Which element has the largest atomic radius Li o C or F?

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.

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.

What is the atomic radius of O?

152 pmOxygen/Van der Waals radius

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 element has a larger atomic radius than sulfur?

CadmiumCadmium has larger atomic radius than sulfur. Explanation: Down a period, atomic radii decrease from left to right due to the increase in the number of protons and electrons across a period: when a proton is added the pull of the electrons towards the nucleus is larger, so the size of the atom decreases.

Does S or O have a larger atomic radius?

Sulfur is in the same Group as oxygen and one Period lower, so its outer electrons occupy orbitals from the n = 3 level while oxygen’s outer electrons occupy orbitals from the n = 2 level. Consequently for the neutral atoms, S would be larger than O.
