Which of the following has the largest radius?
Thus O2− has a minimum z-effective thus largest radius.
Which of the following ion has largest radius?
Ernest Z. K+ has the largest radius.
Which has largest radius CO 3?
c)Fe+3. d)Co+3. Ionic radius of Mn3+ will be largest.
Which of the following has the smallest radius?
Helium has the smallest atomic radius.
Which ION is the largest?
Consequently, the ion with the greatest nuclear charge (Al 3 +) is the smallest, and the ion with the smallest nuclear charge (N 3−) is the largest.
…
Ionic Radii and Isoelectronic Series.
| Ion | Radius (pm) | Atomic Number |
|---|---|---|
| N 3− | 146 | 7 |
| O 2− | 140 | 8 |
| F − | 133 | 9 |
| Na + | 98 | 11 |
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 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+ .
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 .
Which of the following has the largest radius K Na+ Na K+?
K+ has a larger atomic radius than Na+. The Periodic Table is accompanied by many trends. One such trend involves the atomic radius for these elements. As you go down the periodic table, the atomic radius increases which is why K+ has a larger radius… it’s below Na+.
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 element has the largest atomic number?
Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.
What is the atomic radius of RB?
290 pm
