Consider the electron configuration for sodium:
[Na] 1s2 , 2p2 2p6 3s1
and sodium ion
[Na]+, has no electrons in the 3rd shell as the 3s orbital is empty due to the loss of the electron.
Therefore, due to the missing orbital, the size of the ion is much smaller than the neutral atom. This is also true with all cations. Anions on the other hand become larger as they become electronegative, due to electron shielding.
There are three electronic shells in sodium while four in iron so Iron is larger in size. other words to make it shorter it would be the iron
A sodium atom has a net charge of zero. A sodium ion has a net charge of 1+.
No, a silicon atom is larger than a sodium atom. This is because silicon has more electrons and protons than sodium, leading to a larger atomic radius.
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
Yes it is. Calcium atom loses electrons more readily in cell reactions than in reactions with air, water and dilute acids.
A carbon Atom. Sodium Atoms Weigh Less Than Carbon Atoms And Also They Are Smaller Overall.

A sodium atom has a net charge of zero. A sodium ion has a net charge of 1+.
No, a silicon atom is larger than a sodium atom. This is because silicon has more electrons and protons than sodium, leading to a larger atomic radius.
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
A diagram showing the sodium atom as larger than the positive sodium ion would be representative since the positive ion has lost an electron, leading to a decrease in size due to the loss of electron-electron repulsion.
its not
The sodium atom is much bigger than a sodium cation with a plus 1 charge, because the "lost" electron of the ion had a higher principal quantum number than any remaining electron in the ion and therefore was distributed through a larger volume of space than any of the remaining electrons.
The sodium atom loses an electron to chlorine. Chlorine has a higher electronegativity so it attracts the electron from sodium. Sodium now has 11 positive protons holding only 10 electrons whereas chlorine has an extra electron to control. Chlorine has 17 protons holding 18 negative electrons, therefore, its proton to electron ratio has gone down. Sodium's proton to electron ratio went up, therefore, the electrons are closer to the nucleus and the ionic radius is less than the atomic radius.
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
Sodium reacts less vigorously with water compared to potassium because sodium has a larger atomic size and lower reactivity than potassium. This results in a slower reaction rate and less violent release of hydrogen gas.
yes sodiom atom is an isolated one it is the atom of sodium sodium chloride is salt
