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.
Which of the following has the minimum atomic radius?
Fluorine has a minimum atomic radius. The atomic radius of Fluorine is 42 pm.
What species has the smallest radius?
i) Among O, O-, O2- the species O has the smallest radii because the radius of the anion is always larger than the radius of the atom from which it is formed. O-and O2- are anions of oxygen.
Which element has the smallest atomic radius quizlet?
Therefore, rubidium has the largest atomic radius whereas helium has the smallest.
Does carbon have the smallest atomic radius?
The potassium atom has an extra electron shell compared to the sodium atom, which means its valence electrons are further from the nucleus, giving potassium a larger atomic radius.

Which element has a smaller atomic radius lithium or fluorine Why?
3. An atom of fluorine is smaller than an atom of lithium because with more protons the electrons are pulled closer to the nucleus. 4. An atom of fluorine is smaller than an atom of lithium because fluorine has a high ionization energy and will not lose electrons as easily as lithium.
Does P or CL have a larger atomic radius?
Normally, phosphorous has a larger atomic radius compared to sulfur and sulfur has a larger atomic radius compared to chlorine. Even though you are adding electrons to the atoms, the atomic radius of phosphorus is still larger than sulfur and same thing with chlorine.
Which of the following has the largest atomic radius?
So Cesium has the largest atomic radius among the given elements.
Which has smallest size?
Ionic size varies inversely with nuclear charge. Higher the nuclear charge, smaller the radii. Thus P5+ because of the high nuclear charge, has the smallest size.
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.
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 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.
Why does atomic radius increase from right to left?
This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius. Atomic radius increases from top to bottom within a group. This is caused by electron shielding.
Which has largest radius?
Since the atomic radius decreases in a period but increases down the group so Sr of group II and period V is largest in size.
Why does fluorine have a larger atomic radius than oxygen?
Explain why fluorine has a smaller atomic radius than both oxygen and chlorine. Fluorine is keeping it’s electron very close to the nucleus. Making the atomic radius smaller. Atomic radius trend goes from left to right that atomic radius decreases.
