How many valance electrons are in sodium?
none
No of valance electrons in sodium?
Sodium has 1 valence electron in the 3s sublevel.
How can the number of valence electrons be determined from the periodic table?
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
What is the number of valance electrons in oxygen?
six valence electrons
What elements have 2 valance electrons?
The entire Group 2A has 2 valence electrons; this includes sodium and calcium.
What is the number of valance electrons in halogens?
Seven
What is the number of valance electrons for germanium?
4
How can the number of core electrons be detemined from the periodic table?
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
What is the valance number for fluorine?
7 valence electrons
