Use the Periodic Table as a guide. As you go across from left to right the number of valence electrons increases.
H = 1
Be = 2
B = 3
C = 4
N = 5
O = 6
F = 7
This trend stays the same all the way down each column. Usually periodic tables are marked on the top with roman numerals or something to signify how many valence electrons each element has.
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
Phosphorus has 5 valence electrons.
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
There are 16 electrons in an oxygen molecule as each oxygen atom has 8 electrons.
4 electrons in the outer shell 2-8-4 electron configuration :D
6 valence electrons

The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
six valence electrons.....It only requires two more to complete octet....
six valence electrons
Oxygen atoms have 6 valence electrons, while sulfur atoms have 6 valence electrons as well.
2 valance electrons
There are 27 valance electrons.
The oxygen family, also known as Group 16 on the periodic table, has 6 valence electrons. This includes elements like oxygen, sulfur, selenium, and tellurium. Valence electrons are the electrons in the outermost energy level of an atom and are involved in bonding.
Oxygen has 6 valence electrons. A person can determine the number of valence electrons by looking at the periodic table. since oxygen is in the 6th column form the left, it has 6 valence electrons.
Iodine has 7 valance electrons
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
