Na has one valence electron i.e. 1 electron in valence(last) shell.
Sodium (Na) has 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 ion (Na+) has 10 valence electrons and oxygen ion (O2-) has 8 valence electrons.
In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.

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.
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
Sodium ion (Na+) has 10 valence electrons and oxygen ion (O2-) has 8 valence electrons.
In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.
The number of valence electrons increases by one as you move from left to right across a period in the periodic table. Sodium (Na) has 1 valence electron, magnesium (Mg) has 2 valence electrons, aluminum (Al) has 3 valence electrons, silicon (Si) has 4 valence electrons, phosphorus (P) has 5 valence electrons, sulfur (S) has 6 valence electrons, chlorine (Cl) has 7 valence electrons, and argon (Ar) has 8 valence electrons.
N and V have same number of valence electrons.The number of valence electrons is 5. V is a metal while N is a non metal.
Na is the chemical symbol for Sodium. Na charged is an ion, meaning the number of electrons in the atom differs relative to the charge; for instance, Na+ is missing one of its valence electrons and Na- has an additional electron.
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Two valence electrons.
Table salt is sodium chloride and have Na+ and Cl- ions. They have the electronic configuration of Ne and Ar respectively and both have 8 valence electrons.
the number of valence electrons is the number group on the table its on
