Sodium has one valence electron in its outermost shell (the third electron shell). To achieve a stable electron configuration, similar to that of the nearest noble gas (neon), sodium needs to lose this single valence electron rather than gain more. Therefore, sodium does not need additional valence electrons; it only needs to lose its one valence electron to achieve stability.
Sodium iodide (NaI) consists of sodium (Na) and iodine (I) atoms. Sodium has 1 valence electron, while iodine has 7 valence electrons. Therefore, in total, sodium iodide has 1 + 7 = 8 valence electrons.
Every sodium atom has only one valence electron.
Strontium has 2 valence electrons. It is in group 2 of the periodic table, which means it has 2 electrons in its outermost energy level.
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
Zinc has two valence electrons.
Sodium has one valence electron.
Silicon has 4 Calcium has 2 Chlorine has 7 Sodium has 1
Sodium iodide (NaI) consists of sodium (Na) and iodine (I) atoms. Sodium has 1 valence electron, while iodine has 7 valence electrons. Therefore, in total, sodium iodide has 1 + 7 = 8 valence electrons.
It has only 1 valence electron
As is present in group-15. It has 5 valence electrons.
Every sodium atom has only one valence electron.

Sodium's atomic number is 11. To be neutral then, it must have 11 protons and 11 electrons. Since sodium is in group 1, it has 1 valence electron.
Sodium oxide has a total of 8 valence electrons (1 from sodium and 6 from oxygen) because sodium is in group 1 and oxygen is in group 6 of the periodic table.
