Only 1, It's has 3 Energy Levels and only one Electron in it's outermost level.
Sodium has 1 Valence Electrons. remember that in each group 1,2, 13, 14, 15, 16, 17, and 18 every element has the same Valence electrons in each group. Like Group 1 they all have 1 valence electrons. Group 2 has 2, Group 13 has 3, Group 14 all have 4, Group 15 all have 5, Group 16 all have 6, Group 17 all have 7, and finally Group 18 all have 8 valence electrons. the other groups have zero Valence electrons. Got to Touchspin on Google and theres a Periodic Table that has the valence electrons for everything. On the side of the webpage its the second button that has the table.
sodium has 8 valence electrons hint. the number of valence electrons is equal to the group number the element is in
1,2, or 7 im not sure
Edit: the answer is 1 electron in the valence shell, with a valence of 7
Just like the rest of the alkali metals, sodium has one valence electron. This is why sodium is so reactive and has a low ionization energy--it is "eager" to get rid of this valence electron to fulfill the octet rule.
See links/related questions below.
Sodium has 1 valence election, just like all it's friends in the 1A group. Hope this helps!
it needs to lose 1 electron lol, cos it is in group 1
1. Valence electrons are found on atoms outermost electron shell/ energy level.
1: Sodium is in column 1 of a periodic table.
Sodium has 1 valence electron.

Sodium has one valance electron.
It has 8

There are a total of 11 electrons in Sodium.
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 number of protons is the atomic number, which for sodium is 11. The number of electrons in neutral sodium atom is 11 and these are in the following shells:- 1st valence = 2 electron 2nd valence = 8 electrons 3th valence = 1 electrons
sodium belongs to IA group element in periodic table.hence valence is one
one valence electron
A sodium atom has one valence electron.
The order is: Iodine (7 valence electrons) Carbon (4 valence electrons) Calcium (2 valence electrons) Sodium (1 valence electron)
There are a total of 11 electrons in Sodium.
Sodium 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.
The valence electrons are either lost to another atom or the sodium atom gains valence electrons, it really depends on if what the sodium atom is bonding with has a lot or a little of valence electrons. The structure doesn't change though, just the number of valence electrons change. The nucleus is never changed when an ion is formed.
No, sodium has 1 valence electron, not 3.
the number of protons is the atomic number, which for sodium is 11. The number of electrons in neutral sodium atom is 11 and these are in the following shells:- 1st valence = 2 electron 2nd valence = 8 electrons 3th valence = 1 electrons
sodium belongs to IA group element in periodic table.hence valence is one
It has only 1 valence electron
Through the number of electrons in the last (valence) shell. Delete Sodium has the electronic configuration 2, 8, 1; therefore it's valency is 1.
magnesium has 2 outer electrons, its valence is 2+ sodium has 1 outer electrons, its valence is 1+
