Which of these atoms has the largest atomic radius?

So Cesium has the largest atomic radius among the given elements.

Does carbon or silicon have a larger atomic radius?

Size. As expected silicon is larger than carbon due to the presence of a second shell: i.e., C = 1s2 2s2 2p2 while Si = 1s2 2s2 2p6 3s2 3p2. A comparison of the relative sizes of carbon and silicon are given in Table. Atomic, covalent, and van der Waals radii of carbon and silicon.

Divide the distance between the nuclei of the atoms by two if the bond is covalent. For example, if you know the distance between the nuclei of two covalently bonded atoms is 100 picometers (pm), the radius of each individual atom is 50 pm.

Does atomic radius increase from left to right?

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 RB?

290 pm

What is the radius of Rb+?

1.64 …

What is the ionic radius of K+?

280 pm

343 pm

What kind of bonds can cesium form?

Cesium is the most electropositive and most alkaline element, and thus, more easily than all other elements, it loses its single valence electron and forms ionic bonds with nearly all the inorganic and organic anions.

Which ion has the largest size?

Cs+ has highest ionic radii as it is on the extreme right corner of the table. So it is highest in it’s period and highest in the group.

Which group has the largest atoms?

Cesium (Cs), tucked in the lower left hand corner of the table, has the largest known atoms.

Which is larger PB or PO?

1. a) Atomic size decreases from left to right across a period, due to a greater nuclear attraction. Pb and Po both are in same period but Pb lies left to Po in periodic table, so it has the larger radius. Thus, Pb is the larger atom.

Noble gases are nonreactive, nonmetallic elements in group 18 of the periodic table. Noble gases are the least reactive of all elements. That’s because they have eight valence electrons, which fill their outer energy level.

What element is the most difficult to pull an electron away from?

The ionization energy of the elements increases as one moves up a given group because the electrons are held in lower-energy orbitals, closer to the nucleus and thus more tightly bound (harder to remove). Based on these two principles, the easiest element to ionize is francium and the hardest to ionize is helium.

Are valence electrons the most difficult to remove?

Valence electrons are most difficult of all electrons to remove. Core electrons are the easiest of all electrons to remove.

What kind of elements has the greatest tendency to attract?

Inert gasses or noble gasses on the right side of the periodic table are the element which most likely attract electrons. It’s because the nuclear charge for the elements in the right side of the periodic table is higher, and the atom of inert gases or noble gases is the greatest attraction for electrons.
