How many valence electrons does sodium electrons?

Answer 1

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.

Sodium has 1 valence election, just like all it's friends in the 1A group. Hope this helps!
