Question
(a)
What is the maximum number of electrons in an atom that can have the following quantum numbers?
(c) n = 7, l = 6, ml = +5
(d) n = 6, l = 3, ml = -2, ms = +1/2
(b) For each of the molecules or ions whose formulas are given below draw a single Lewis structure which obeys the octet rule. Calculate the formal charges on all of the atoms in these Lewis structures.
What is the formal charge on one O atom?
-1
0
+1
+2
+3
(b) NF3
What is the formal charge on one N atom?
-1
0
+1
+2
+3
What is the formal charge on one F atom?
-1
0
+1
+2
+3
What is the formal charge on one O atom?
-1
0
+1
+2
+3
Explanation / Answer
(a) 2 electrons
(b) 1 electron
NF3 :
formal charge = valancy- non bonding electrons- - 1/2 (bonded electrons)
N formal charge = 5 - 2 - (6 )/2 = 0
N formal charge = 0
F formal charge = 7 - 6 - 1/2 (2) = 0
F formal charge = 0
note : i can see these only . question and options are here but there is no molecule here. only NF3 i can see here
