Answer:
(a) The nitrogen atom in contains 8 electrons surrounding the central nitrogen atom.
(b) The nitrogen atom in has 8 electrons around the central nitrogen atom.
(c) The nitrogen atom in has 8 electrons surrounding the central nitrogen atom.
Explanation:
The Lewis dot structure illustrates the connections between atoms within a molecule, additionally showing unpaired electrons present in the molecule.In this structure, valence electrons are represented as 'dots'.
Now we will determine the number of electrons linked to the central nitrogen atom in the specified molecule.
(a) The identified molecule is,Recognizing that nitrogen has '5' valence electrons while hydrogen has '1', we ascertain the total valence electrons in
From the Lewis structure, we conclude that the nitrogen atom in
(b) The identified molecule is,
Knowing that nitrogen has '5' valence electrons and hydrogen has '1' valence electron, the total number of valence electrons for = 5 + 4(1) - 1 = 8
contains 8 electrons surrounding it.
(c) The identified molecule is,
= 5 + 3(1) = 8Utilizing the Lewis dot structure indicates there are 6 bonding and 2 non-bonding electrons.
According to the Lewis dot structure, we conclude that the nitrogen atom in
has 8 electrons surrounding it.
