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.
Two valence electrons in the formula unit.
Silicon has a total of 10 core electrons and 4 valence electrons.
26 because phosphorous has five valence electrons and flouride has seven times three.
The symbol An doesn't exist.
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.
6 valence electrons
electrons in Na2O
14 total electrons. 5 valence electrons.
Si (silicon) is in the fourth group, has 14 total electrons, and four valence electrons.
Silicon has a total of 10 core electrons and 4 valence electrons.
15 total electrons, 3 valence electrons
6 total valence electrons. go apex!
NO2 Nitrogen has 5 valence electrons Oxygen has (6*2) =12 valence electrons therefore, the total number of valence electron =12 +5 = 17valence electrons.
26 because phosphorous has five valence electrons and flouride has seven times three.
The symbol An doesn't exist.
there are four valence electrons in tin/
Sulphur has 16 electrons. Correction: there is 16 in total, but 6 in the outer (valence) shell.
c=4 valence electrons S=6 valence electrons but since its S2 you times 6 by 2=12 12+4=16 16 valence electrons total for CS2
