## Which has a larger atomic radius K or RB?

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.

## Is RB larger or smaller than K?

Your ques is incorrect the atomic size of rubidium is greater than that of potassium because of the addition of number of shells as we move down a group. Yo can learn more about this by searching about trends in atomic size on google.

**Does RB have the smallest radius?**

For example, in the first group, the Atomic radius trend from smallest to greatest is: H (smallest) — Li — Na — K — Rb — Cs — Fr (greatest). And since the size of atom is mostly consist of electrons, more energy level is filled, the larger the atom will be.)

### What is the atomic radius for K?

280 pm

Potassium/Van der Waals radius

### Which is bigger K or K+?

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+.

**Which has the smallest atomic radius?**

Helium

Helium 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.

#### What is the atomic size of Rb?

290 pm

Rubidium/Van der Waals radius

#### Which one has greater size Na or K?

K+ is larger than Na+ because the ionic radius increases in a particular group on moving from top to bottom due to increase in the principle energy shell though the number or electrons in the valence shell remain the same.

**Is k or k 1 smaller?**

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+.

## Which is smaller in radius potassium or rubidium?

Potassium’s atomic radius is smaller than rubidium’s because potassium has fewer energy levels of electrons. Potassium’s atomic radius is smaller than rubidium’s becausepotassium has fewer energy levels of electrons. Potassium has the smaller radius.

## Which is the smallest element with the smallest radius?

Potassium’s atomic radius is smaller than rubidium’s becausepotassium has fewer energy levels of electrons. Potassium has the smaller radius. Q: Which has the smallest radius K Rb K Rb?

**How is the van der Waals radius of an atom determined?**

The van der Waals radius (also known as the nonbonding atomic radius) is the radius of an atom which is not bonded to other atoms; this is determined by measuring the distance between atomic nuclei which are in direct but nonbonding contact with each other in a crystal lattice.

### What is the atomic radius of boron and lithium?

Atomic radius of Lithium (Li) 182 pm. 4. Atomic radius of Beryllium (Be) 153 pm. 5. Atomic radius of Boron (B) 192 pm. 6.
