The NCl3 molecule, like most other stable molecules, exist because they share electrons in such a way as to close out the valence shell. Therefore, although one usually doesn't say so in regards to molecules, NCl3 has 8 valence electrons.
Silicon has a total of 10 core electrons and 4 valence electrons.
HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.
26 because phosphorous has five valence electrons and flouride has seven times three.
A total of 7 valence electrons. If I remember correctly, the number of valence electrons of all group A elements are designated by their group number. Chlorine is in group VIIA, hence 7 valence electrons.
The symbol An doesn't exist.

14 total electrons. 5 valence electrons.
Silicon has a total of 10 core electrons and 4 valence electrons.
Si (silicon) is in the fourth group, has 14 total electrons, and four valence electrons.
15 total electrons, 3 valence electrons
Sulfur (S) has 6 valence electrons. The S2- ion gains two electrons, bringing the total to 8 valence electrons.
NO2 Nitrogen has 5 valence electrons Oxygen has (6*2) =12 valence electrons therefore, the total number of valence electron =12 +5 = 17valence electrons.
HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.
There are 14 valence electrons in I2. Each iodine atom contributes 7 valence electrons, resulting in a total of 14 valence electrons in the diatomic molecule.
A carbon atom has 4 valence electrons. So, for a C6 molecule, there will be a total of 6 carbon atoms, and each carbon atom will contribute 4 valence electrons, giving a total of 24 valence electrons in the C6 molecule.
Each H has 1. Each O has 6 and the S has 6. That's a total of 32 valence electrons.
Xenon pentafluoride (XeF5) has a total of 8 valence electrons. Xenon (Xe) contributes 8 valence electrons, while each fluorine (F) atom contributes 7 valence electrons. The 5 fluorine atoms in XeF5 contribute a total of 35 valence electrons.
