There is one valence electron in a neutral sodium atom. Sodium has an electron configuration of 2-8-1, indicating it has one electron in its outermost energy level.
A sodium atom has 1 electron in its valence shell, while a chlorine atom has 7 electrons in its valence shell. When sodium reacts with chlorine to form sodium chloride, the sodium atom loses its 1 electron to achieve a stable octet configuration, while the chlorine atom gains this electron. The resulting sodium chloride molecule has 8 electrons in the valence shell of the chlorine atom.
Both a neon atom and a sodium ion have 10 electrons. Neon is a noble gas with a full valence shell, while a sodium ion has lost one electron to achieve a stable electron configuration.
Since sodium has atomic number 11, its electronic configuration is untill 3s1. This means the valence shell has 1 electron, so it has 1 valence electron.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.

A sodium atom has one valence electron.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
An atom of sodium has one valence electron. When a sodium atom loses this electron to another atom, it becomes a sodium ion.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
Two sodium atoms are needed to provide the 2 electrons necessary to complete the valence octet of an oxygen atom. Sodium typically loses one electron to achieve a stable electron configuration, which can then be transferred to an oxygen atom to satisfy its electron needs.
The electron-dot structure of sodium atom is 'Na-dot' or 'Na.' One dot is one valence electron.
When a sodium atom loses a valence electron, it becomes a positively charged particle known as a sodium ion (Na⁺). This process occurs because the loss of an electron results in more protons than electrons, giving the atom a net positive charge. Sodium typically loses one electron to achieve a stable electron configuration similar to that of noble gases.
If a sodium atom loses its only valence electron, it becomes a sodium cation (Na+). This is because it has lost a negative electron, leaving behind a positively charged ion.
