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.
A sodium atom has 1 valence electron. Sodium belongs to group 1 of the periodic table, which means it has 1 electron in its outer shell.
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.
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.
An atom of sodium has one valence electron. When a sodium atom loses this electron to another atom, it becomes a sodium ion.
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 valence electron configuration for a magnesium atom is 3s^2. Magnesium is in group 2 of the periodic table, so it has 2 valence electrons in the 3s orbital.
A Lewis structure for a sodium atom typically shows the symbol "Na" with one valence electron represented as a dot. Sodium has one valence electron in its outermost shell.
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.
