Quick Answer: Which Elements Has The Greatest Atomic Radius?

Which metal has the smallest atomic radius?

HeliumHelium has the smallest atomic radius.

This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus.

Atomic radius decreases as you move across a period from left to right and decreases as you move up a group from bottom to top..

What is the atomic radius of B?

180 pmBoron/Van der Waals radius

What is magnesium’s atomic radius?

173 pmMagnesium/Van der Waals radius

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.

Is Br or Br bigger?

Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.

What is the atomic radius of F?

147 pmFluorine/Van der Waals radius

Which of these has the greatest atomic radius?

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 a larger atomic radius O or C?

Since C comes before O in the second period, O will have a smaller atomic radius than C .

Which element has lowest atomic radius?

heliumAtomic 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.

How many types of atomic radius are there?

three typesAtomic radii are divided into three types: Covalent radius. Van der Waals radius. Metallic radius.

What is the atomic radius of CI?

126 pmIron/Atomic radius
