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 of the following has largest radius 1s2?
Answer and Explanation:
While all of these ions and atoms have the 1s22s22p63s23p6 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 electron configuration due to the gain or loss of electrons by ions, (3) the sulfide ion S2− has the largest radius.
Which has largest radius?
Thus O2− has a minimum z-effective thus largest radius.
Which element has a larger atomic radius than phosphorus?
Atomic Radius of the elements
| Helium | 31 pm | 161 pm |
|---|---|---|
| Phosphorus | 98 pm | 183 pm |
| Selenium | 103 pm | 184 pm |
| Xenon | 108 pm | 185 pm |
| Silicon | 111 pm | 188 pm |
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) | → |
Which of the following has largest radius mg2+ Na+ O2?
d- F- Ionic radius increases with increase in positive charge on isoelectronic species. Here, Mg+2 will have largest ionic radius.
Which has the largest radius Co3+ Mn3+ ni3+ Cr3+?
Fe 3+ has highest radii because by going left to right in the periodic table , the size get decreased so .. Fe 3+ >Co3+ >Cr3+ >Mn3+ .
Which of the following has the largest radius FCNO?
As we can see, only Potassium has four electron shells, therefore Potassium has the largest atomic size. Showing once again how Potassium has the largest atomic radius, and therefore the largest atomic size.
Which has a larger radius Na or Na 1?
Ne will have bigger radius than Na+1 because in Ne there are equal number of electrons and the number of protons. … So due to the increased nuclear charge, as compared to the neutral Na atom, the stable configuration of Na atom gets disturbed and the electrons are pulled towards the nucleus.
Which has a larger radius F or F?
F has a larger radius than F− because an additional electron causes greater repulsion in F.
Why is the ionic radius of K+ smaller than CL?
Answer: 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.
Is phosphorus atomic radius is smaller than magnesium atomic radius?
(a)- Magnesium has a larger atomic radius due to a smaller effective nuclear charge. (b)- Phosphorus has a larger atomic radius due to a larger effective nuclear charge. … The atomic size of the elements can be explained by the factor of the nuclear charge.
What element in the second period has the smallest atomic radius?
Explanation: It’s F fluorine. It has the smallest diameter in the second period. In the same period diameter of atom depends on how many electrons are in outer layer.
