Explanation: Helium has the smallest atomic radius.
What element has the smallest 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.
Which of the following has smallest radius?
Hence, Cl has the smallest radius.
Which element has the smallest atomic radius quizlet?
Therefore, rubidium has the largest atomic radius whereas helium has the smallest.
Which of the following four elements has the smallest radius?
In general, atomic radius decreases from left to right across the period but increases down a group. Hence, francium is expected to have the biggest atomic size while fluorine is the smallest.
What is the atomic radius of RB?
290 pm
Which element has the largest atomic radius as NP?
Antimony(Sb) has the largest atomic radius because it has more number of shells as compensation to the other elements..
Which element in Group 2 has the largest radius?
Trends in Atomic Radius of Group 2 Elements
| name | atomic radius (pm) | Trend |
|---|---|---|
| magnesium | 160 | ↓ |
| calcium | 197 | ↓ |
| strontium | 215 | ↓ |
| barium | 217 | largest |
How do you find atomic radius?
The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it. The left hand diagram shows bonded atoms.
Which of the following has largest atomic radius?
So Cesium has the largest atomic radius among the given elements.
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.

Trends in Atomic Radius of Group 1 Elements
| name | atomic radius (pm) | Trend |
|---|---|---|
| sodium | 186 | ↓ |
| potassium | 425 | ↓ |
| rubidium | 244 | ↓ |
| caesium | 262 | largest |
Does CA or NI have a larger atomic radius?
Ca or Ni: the atomic radius of calcium is 194 pm while that of nickel is 149 pm.
What is the atomic radius of Na?
227 pm
Why does atomic radius increase down a group?
In general, atomic radius decreases across a period and increases down a group. … Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
