Antimony(Sb) has the largest atomic radius because it has more number of shells as compensation to the other elements..
Which element has the 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.
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 element has the largest atomic radius quizlet?
Therefore, rubidium has the largest atomic radius whereas helium has the smallest.
Which element has the atomic radius?
The atomic radius of a chemical element is the distance from the centre of the nucleus to the outermost shell of an electron.
…
Atomic radius.
| symbol | Br |
|---|---|
| name | bromine |
| van der Waals | 185 |
| Covalent (single bond) | 114 |
| Covalent (triple bond) | 110 |
What has the smallest atomic radius?
Explanation: 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 element has the second largest atomic radius?
(A) Trends in the Atomic Radius of Elements in Period 2
| Element | Li | Be |
|---|---|---|
| Energy Level being filled (Valence Shell) | second (L) | second (L) |
| Nuclear Charge (charge on all protons) | 3+ | 4+ |
| Atomic Radius (pm) | 134 | 90 |
| General Trend | (largest) | → |
Why is atomic radius not a well defined quantity?
The exact measure of atomic radius is not easy due to following reasons: (i) The atom does not have well defined boundary. the probability of finding the electron is never zero even at large distance from the nucleus. (ii) It is not possible to get an isolated atom.
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 element in period three has the largest atomic radius?
- Atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. …
- Considering this trend Sodium is having a highest atomic radius in 3rd period.
Which has larger atomic radius Cl or Br?
Likewise, bromine will have a larger atomic radius when compared with chlorine. … 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.
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 atom has the largest atomic radius in Group 18?
Thus radon has largest atomic radius.
What is the atomic radius for hydrogen?
120 pm
Why does the atomic radius decrease as electrons are added to a shell?
Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.
What is magnesium’s atomic radius?
173 pm
