Electrons & Oxidation

Is Ca+ more stable than Ca2+?

Calcium ion is more stable as it has completed its octet or it have lose electrons to get 8 electrons in last shell,valence shell. Calcium atom is more reactive than a calcium ion. Aakash EduTech Pvt.

Is Ca2+ smaller than AR?

Ca2+ vs. Ar: Ca has a +20 nucleus, Ar’s is +18. Thus Ar will have a smaller Zeff (=+18-10 = +8 vs. +20 – 10 = +10 for Ca2+) and a larger radius.

Why is Zn2+ smaller than Ca2+?

Zn2+ is greater in size than ca2+. No. of shells increases down the group. As you move down a group in the periodic table , additional layers of electrons are being added, which naturally causes the ionic radius to increase as you move down the periodic table.

Is Mg2+ smaller than Na+?

Mg2+ is smaller than Na+ because of two reasons . It is located to right of the Na+ atom in the 3rd Period and it also has +2 charge on it. Mg2+ is larger than Be2+ because Mg comes down in the group.

Is Li+ smaller than Na+?

Similarly Li+ would be the smallest because it has only 2 electrons and therefore the least electron- electron repulsion. When comparing F- and Na +, we have to be careful, as both of them have 10 electrons. So Na+ is smaller due to the larger attractive force of the protons.

Is Mg2+ bigger than na?

(i) The sodium ion (Na+) is larger than the magnesium ion (Mg2+) due to two effects.

What is the radius of Mg2+?

Metallic, Covalent and Ionic Radii(r)*

What is Be2+ radius?

Ionic radius of Be2+ is _than Becc11..

What is the atomic radius of K+?

280 pm

What is the radius of Na+?

227 pm

Why is the radius of Na+ smaller than O2?

In other words, effective nuclear charge, or Zeff , increases when electrons are removed from an atom. This means that the electrons now feel a greater attraction force from the nucleus, hence they are pulled tighter and the size of the ion is smaller than the size of the atom.
