Which of the following ions has largest ionic radius?

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

Which of the ions has the largest ionic radius?

Thus, the ionic radius of Cs+ is the largest.

Which of the following ions has largest radius?

Here, Mg+2 will have largest ionic radius.

Which of the following ion with largest ionic size is?

Cs+ has highest ionic radii as it is on the extreme right corner of the table.

How do you determine the largest ionic radius?

In general:

  1. Ionic radius increases as you move from top to bottom on the periodic table.
  2. Ionic radius decreases as you move across the periodic table, from left to right.

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.

Which one has the largest radius?

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 ion has the smallest radius quizlet?

S2-, K+, and Ca2+ all have 18 electrons. Which ion would you expect to have the smallest ionic radius? Ca2+ would have the smallest ionic radius because Calcium has a positive charge, and because this ion is a cation, cations will have the smallest radius.

Which of the following ionic radius is correct?

It is known that radius of a cation is always smaller than that of a neutral atom due to decrease in the number of orbits. Whereas the radius of anion is always greater than a cation due to decrease in effective nuclear charge. Hence the correct order is H->H>H+.

Which ion has the largest radius Se2 F O2 Rb+?

Answer. Answer: The answer is “Rubidium Rb+”.

Which ion is 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

Is Br or I bigger?

Because Iodine has the greatest atomic number, it has a larger radius. This rules out Br and Cl. I- is Iodine in the 1- oxidation state. This means that is has 1 extra electron, and its radius is therefore greater than I.

What has the highest value in the ion?

Which one of the following ions has the highest value of ionic radius? This can be explained on the basis of z/e, where as z/e ratio increases, the size decreases and when z/e ratio decreases the size increases. z is atomic number and e is number of electrons. The correct option is C.
