1) calculate the number of valence electrons in nitrogen trichloride, ncl₃. valence electrons
1) calculate the number of valence electrons in nitrogen trichloride, ncl₃. valence electrons
Answer
Explanation:
Step1: Determine valence electrons of nitrogen
Nitrogen ((N)) is in group 15 of the periodic table. The number of valence electrons for an element in group (n) is (n - 10) (for (n> 10)). So for (N), valence electrons (=5).
Step2: Determine valence electrons of chlorine
Chlorine ((Cl)) is in group 17. Valence electrons for (Cl=7).
Step3: Calculate total valence electrons in (NCl_{3})
In (NCl_{3}), there is (1) (N) atom and (3) (Cl) atoms. Total valence electrons (=1\times5 + 3\times7) (=5 + 21) (=26)
Answer:
(26)
