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+ .
Which of the following has largest radius?
Answer. Fe3+ has the largest radii. The atomic radius is calculated with the increase in the number of the electronic shells which.
Which has largest radius among Co 3 Mn 3 CR 3 NI 3?
d)Co+3. Ionic radius of Mn3+ will be largest.
What ion has the largest radius?
1 Answer. Ernest Z. K+ has the largest radius.
Which of the following has the smallest radius?
Helium has the smallest atomic radius.
Which is larger F or Na+?
Na+ has smaller size than F- because both Na+ and F- have equal number of electrons i.e.10 . After losing an electron Na will have less electron cloud and more effective nuclear charge whereas F after gaining an electron will have less effective nuclear charge than the parent atom so the size increases .
What is the radius of mg2+?
Metallic, Covalent and Ionic Radii(r)*
| Atom/Ion | r(pm) |
|---|---|
| Lu3+ | 86 |
| Mg | 160 |
| Mg2+ | 72 |
| Mn | 137 |
What is the radius of Be2+?
Ionic radius of Be2+ is _than Becc11..
What is the radius of Na+?
227 pm
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.
Which has the largest radius O or O 2?
O2− is larger than O because the increase in electron repulsions that accompany addition of an electron causes the electron cloud to expand. O2− is larger than O because O is neutral but O2− has a charge 2−. … S2− is larger than O2− because for particles with like charges, size increases going down a family.
Which ion has the smallest radius?
As Oxygen is present at the top of the group, therefore, it has the smallest radius due to less number of shells.
What is the atomic radius of RB?
290 pm
How do you determine 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.
