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 (Na) has one valence electron.
Na has one valence electron i.e. 1 electron in valence(last) shell.
The ion Na+ has 11 protons, 12 neutrons, and 10 electrons. This is because sodium has an atomic number of 11, meaning it naturally has 11 protons and 11 electrons, but as an ion with a +1 charge, it has lost 1 electron.
The cation of sodium has 11 protons and 10 electrons.
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.

Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
One. Sodium is found in Group 1, which is characterized by having one valence electron, so by extension, potassium, rubidium, cesium, and francium also have one valence electron.
Na has 11 protons and 12 neutrons and 11 electrons.
The NCl3 molecule, like most other stable molecules, exist because they share electrons in such a way as to close out the valence shell. Therefore, although one usually doesn't say so in regards to molecules, NCl3 has 8 valence electrons.
The electron dot method, also known as Lewis dot structure, represents the valence electrons of an atom. For sodium (Na), there is one valence electron, represented as a dot. For bromine (Br), there are seven valence electrons, six of which are represented as dots surrounding the Br symbol, with one dot paired on one side.
Answer: 28 protons 28 electrons; the number of neutrons depends on each isotope of Na and Cl considered.
The atomic number of sodium is 11 which means it has 11 protons and 11 electrons.
