Explanation of Solution
a) Atom—
The number of valence electrons in
atom is
So, there are
So, the Lewis structure for
b) Ion—
The number of valence electrons in
So, there are
So, the Lewis structure for
is as follows:
c) Atom—
The number of valence electrons in
atom is
So, there are 3 lone pairs present.
So, the Lewis structure for
is as follows:
d) Ion—
The number of valence electrons in
So, there are
So, the Lewis structure for
is as follows:
e) Atom—
The number of valence electrons in
atom is
So, there are
So, the Lewis structure for
is as follows:
f) Ion—
The number of valence electrons in
So, there are
So, the Lewis structure for
is as follows:
g) Atom—
The number of valence electrons in
atom is
So, there are no lone pairs present.
So, the Lewis structure for
is as follows:
