Na (Atomic number: 11; Electronic configuration: 1s2, 2s2, 2p6, 3s1).
Na has 11 electrons distributed in electron shells. This negative charge provided by electrons is countered by 11 protons present in nucleus of Na. The electron in 3s1 is losely held by the positively charged nucleus. When Na loses its outermost electron (3s1), there is an imbalance in the total number of positive charge (provided by protons) and negative charge (provided by electrons). With an increase in positive charge in the ion, the electron charge around the nucleus is drawn closer to it. As a result of this the atomic radius of the Na ion decreases and hence its radius is smaller than that of Na atom.
The sodium ion has a positive charge and is formed from a neutral atom by losing its only valence shell electron, thereby giving it a smaller size than its corresponding neutral atom. The chloride ion has a negative charge and is formed from its neutral atom by acquiring an additional electron, thereby somewhat increasing its size.
We are working on this in Physical Science class. A negative ion is larger then its parent atom. A positive ion is smaller then its parent atom. =]
A positive ion is smaller than its parent atom because it has less electrons than its parent atom. The reduced number of electrons are then pulled more tightly to the positive nucleus because the number of protons remains the same, and these now exceed the electrons in number.
Yes, the size of a cation is smaller than it's neutral atom. This is so because cations have a low number of shells and hence a high effective nuclear charge which causes them to be smaller in size then their neutral atoms.
A cation is smaller than the neutral atom because one electron is removed from the original atom to form it. An anion is larger than the neutral atom because one electron is added to the original atom to form it.
The size of the Radius of a positve ion is smaller than a neutral atom because the postive ion has lost electrons, which means the outer most shell might be lost as well making the positve ion smaller and the nuetral atom remains the same

Its atom size is bigger than Chlorine but smaller than Iodine

No, it is not possible because the size of an atom is smaller than the wavelength of light.
It is NOT greater. It is smaller. This is because the Hydrogen ion has lost its electron from the atom and is thus smaller. The hydrogen ion is a proton.
The size of a negative ion is larger than atom. This makes more negative than positive, allowing the negative electrons to go farther from the nucleus.
The Universe was never smaller than an atom.
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
The size of the Radius of a positve ion is smaller than a neutral atom because the postive ion has lost electrons, which means the outer most shell might be lost as well making the positve ion smaller and the nuetral atom remains the same
