Sodium atom |
Sodium-ion |
|
Sodium atom is electrically neutral. |
Sodium-ion is positively charged. |
|
In sodium atom, there are 11 protons and 11 electrons, i.e. an equal number of protons and electrons. |
In sodium-ion, there are 11 protons but 10 electrons, i.e. sodium ion contains a lesser number of electrons. |
|
The sodium atom has only one electron in its valence shell. |
Sodium-ion has 8 electrons in its valence shell. |
|
The size of a sodium atom is larger than a sodium ion. |
