QJEEM19Ch87d3: JEE Main 2019 Chemistry - Class 11 JEEM19Ch87d3 Solution: The group number, number of valence electrons, and valency of…
The group number, number of valence electrons, and valency of an element with atomic number 15, respectively, are:
Multiple Choice Options
- A 16, 6 and 3
- B 15, 6 and 12
- C 16, 5 and 2
- D 15, 5 and 3
Step-by-Step Verified Solution
P[15] = [Ne] 3s23p3
Group number = 10 + valance shell electron = 10 + 5 = 15
number of valence electrons = 5
Valency = 3
Group number = 10 + valance shell electron = 10 + 5 = 15
number of valence electrons = 5
Valency = 3
