Problem 3P
How many valence electrons do the following atoms have?
a. boron b. nitrogen c. oxygen d. fluorine
ANSWER:
Solution:
Here we have to find the number of valence electrons present in the following atoms
a. boron b. nitrogen c. oxygen d. fluorine
Step 1
(a)Boron (B)
The number of valence electrons can be obtained from the electronic configuration of the atom.
The electronic configuration of 5B is 1s2 2s2 2p1
Thus number of valence electrons present in B is 3.
