Which ion has a larger radius? Student Doctor Network
In the sections below we will consider the trends in the atomic radius of period 2 elements, and, of period 3 elements. (A) Trends in the Atomic Radius of Elements in Period 2 Use the data given in the table below to find patterns (trends) in... The factors playing into the strength of an ion's charge density are therefore the charge of the ion (e.g. 2+ for Mg, 1+ for Na) and the effective volume which that charge acts over - which is where the ionic radius comes in. (Note this is different to atomic radius.)
Trends in the Periodic Table HowStuffWorks
An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. In general, the size of an atom will decrease as you move from left to the right of a certain period....Anions of a given element have a larger radius than the neutral atom, so P 3-will increase in size compared with the P atom. (iv) Chlorine is a Group 17 element so its only ionic state is Cl - .

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. Therefore, the chloride anion will have the larger atomic radius. how to watch 2018 opening olympics ceremony 2009-11-07 · The bigger the nuclear charge( the number of proton) , the smaller is the size. So, just find out the number of proton for each species and you should know the answer. joeyeehung · 9 years ago. How to tell if your timing chain is broken

Which element in each pair has atoms with a larger atomic radius? For the representative elements (main group elements), atomicradius generally decreases from left to right across a period.
- 2010-12-02 · Hey guys ive got a question and im not sure how to go about answering it without looking up a table of characteristics of elements! Niobium has an atomic radius …
- That is, elements with a large density have a low specific heat value. This means that the elements with the lowest specific heat value are located in the middle of the bottom rows of the periodic table, exactly where the densest elements are located.
- 2015-01-30 · Same thing goes for the chloride ion, fewer protons means less effective pull, and if you add another valence electron, it shields its neighbors and they all feel less effective overall pull, so I believe the chloride ion will have a slightly larger radius than the chlorine atom.
- The ionic radius is half the distance between two gas atoms that are just touching each other. Values range from 30 pm to over 200 pm. In a neutral atom, the atomic and ionic radius are the same, but many elements exist as anions or cations.
