The Periodic Table : Example Question #2. Which element has the smallest atomic radius? Explanation: Helium has the smallest atomic radius.
Which atom 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.
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 of the following ion has smallest radius?
The ionic radius of Ni2+ is minimum.
Which element has the smallest atomic radius quizlet?
Therefore, rubidium has the largest atomic radius whereas helium has the smallest.
Which element has the largest atomic number?
Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.
What element in the second period has the largest atomic radius?
The element in the second period that has the largest atomic radius is the Lithium (Li).
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 has smaller size O or O2?
Answer. Answer: O2− is larger than O because the increase in electron repulsions that accompany addition of an electron causes the electron cloud to expand. O2− is larger than O because O is neutral but O2− has a charge 2−.
Which ion has the largest radius?
1 Answer. Ernest Z. K+ has the largest radius.
Which of the following cation has the smallest radius?
Among Li+ and Be2+; Be2+ is smaller in size due to high effective nuclear charge.
Which element has an ion with a radius that is larger than its atomic radius?
Anion or negative ion: An atoms gains one or more electrons to form an anion, making the ion larger than the neutral atom. Nonmetals often form anions, so their ionic radius tends to be larger than their atomic radius. This is particularly noticeable for the halogens.
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.

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 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.
