## Which of the following has largest atomic radius?

So Cesium has the largest atomic radius among the given elements.

## Which element in group 3 has the largest atomic radius?

Therefore Sodium (Na) has the largest atomic radius.

## Which element has the largest atomic radius Asnpsb?

• Answer : ‘Sb’ is the element which has the greatest atomic radius.
• Explanation :
• The general trend of the atomic radium of the element is that,
• Hence, ‘Sb’ is the element which has the greatest atomic radius.

## Which metal has the smallest atomic radius?

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. 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.

## 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.

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.

## Which element has the largest atomic radius Na Mg K Ca?

Answer: Potassium (K) with an atomic number of 19 has the largest atomic radius. This is because sodium and potassium are elements of group 1. On moving from top to bottom in a group, the atomic radius increases.

## Why is the ionic radius of K+ smaller than CL?

In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation.

## Why does sodium have a larger atomic radius than aluminum?

Of protons in aluminium(13) is more than sodium(11). That means the nuclear charge of aluminium is more and the electrons are pulled more ‘tightly’ as compared to sodium. Sodium on the other side has less nuclear charge as compared to aluminium and so the electrons are held comparatively loosely.

## Does atomic radius increase Period 3?

Explanation of this trend

Going across period 3: the number of protons in the nucleus increases so … … therefore the force of attraction between the nucleus and the electrons increases … and the atomic radius decreases.

## Which best explains why ionization energy tends to decrease?

The ionization energy decreases because the full s orbital shields the electron entering the p orbital. … Electrons get farther from the nucleus. When electrons are removed from the outermost shell of a calcium atom, the atom becomes. a cation that has a smaller radius than the atom.

## Which halogen has the largest atomic radius?

(B) Trends in the Atomic Radius of Group 17 (VIIA, Halogens) Elements

Element Atomic Number (Z) Trend
fluorine 9 (smallest) ↓
chlorine 17
bromine 35
iodine 53 ↓ (largest)

## Which element has the smallest atomic radius calcium potassium scandium titanium?

The given elements potassium, calcium, scandium, and titanium all belongs to third period. Therefore, out of these elements potassium is at the extreme left and titanium is towards the right. Thus, we can conclude that titanium is the element which has the smallest atomic radius.
