Which has the largest atomic radius Br or Cl?

Likewise, bromine will have a larger atomic radius when compared with chlorine.

Which has greater atomic size Cl or Br?

So the distance between the electrons in the outer shell and the nucleus increases, thus decreasing the nucleic attraction on those electrons. Chlorine is above Bromine in Group 17. So Bromine has a bigger atom with one more electron shell than Chlorine.

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 has a larger atomic radius CL or CL?

Explanation: Chlorine has a proton number of 17. … Hence, we can deduce that the forces of attraction exerted on the outermost electron in chloride ion is lesser than chlorine atom, since there are more electrons. Conclusion, chloride ion has a bigger atomic radius due to an increase in number of electrons.

Which has largest atomic radius?

Atomic 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.

Why is Br more reactive than CL?

Although the bromine nucleus is more positively charged than the chlorine nucleus, the increase in the radius and the extra shielding in the bromine atom outweigh this factor, which means that an electron is more easily attracted into the outer shell of a chlorine atom than that of a bromine atom, so chlorine is more …

Which has larger size k or k+?

These are electrons with “highest energy level”. When at neutral, the potassium ion in the form of K has an 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+.

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.

Which one has the largest size BR I CL?

Why iodine has a largest size among ,Br,I,I-,Cl.

Is BR bigger than F?

The difference between the size of similar pairs of ions actually gets even smaller as you go down Groups 6 and 7. For example, the Te2- ion is only 0.001 nm bigger than the I- ion.
…

Why is CL larger than Na+?

Na atoms are larger than Cl atoms because the electron cloud of Cl is pulled in more tightly by the increased number of protons in the nucleus. Na+ ions are smaller than Cl- ions because the Na+ ions have electrons in only two energy levels and Cl- ions have electrons in three levels.

Which is smaller Na+ or mg2+?

mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus. …

Which is smaller mg2+ or Al3+?

As you go from Na+ to Mg2+ to Al3+, the number of protons in the nucleus increases and so pulls the outer electrons in more and more. … The smallest ion will be the one with the largest number of protons – Al3+; the biggest, the one with the least protons – N3-.

Which has the largest atomic radius lithium or potassium?

Lithium has an atomic number of 3. It can be accomodated in 2shells. Because of the large atomic sells of Potassium, it’s atomic radius is Much larger than that of Sodium or Lithium.

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 RB?
