What are valence electrons in Ne 3s23p4?
2+4= 6 valence electrons
How much valence electrons do berylium got?
Beryllium has two valence electrons.
Why 'he' and 'ne' have zero valency?
He and Ne have no valence electrons, they have fully filled up shells: resp. 2 and 8 in the outer (valence) shell. There is nothing to add or abstract to get it better than it already is.
What element has 4 valence electrons and 3 shells?
Silicon. Electronic configuration [Ne]3s23p2
What is valency of an element having atomic number 20?
H, Li, Na, K = 1valence electrons Be, Mg, Ca = 2 valence electrons B, Al = 3 valence electrons C, Si = 4 valence electrons N, P = 5 valence electrons O, S = 6 valence electrons F, Cl = 7 valence electrons He, Ne. Ar = 0 because they are noble gases and all their electron shells are full

Beryllium has two valence electrons.
How many valence electrons does a chlorine atom have if its electron configuration is Ne3s23p5?
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
Why 'he' and 'ne' have zero valency?
He and Ne have no valence electrons, they have fully filled up shells: resp. 2 and 8 in the outer (valence) shell. There is nothing to add or abstract to get it better than it already is.
How many valence electrons does radon have?
Radon has 8 valence electrons (electrons in it's outer shell) so does Ne, Ar, Kr, Xe. Helium is in the same line, but only has 2 valence electrons. Hope that helps! Sarah G.
What is the number of valence electrons in table salt?
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.
How many valence electrons does a chlorine atom have if its electron configuration is Ne 3s2 3p5?
Seven.

What is the valence electron configuration for the phosphorus atom?
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
How many valence electrons are there in the sulfite ion?
8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.
