Concept explainers
(a)
Interpretation:Whether there is any box in the table in model 5 having N atom with zero bonds and 3 lone pairs.
Concept introduction:Losing 1 electron around an atom from its ground state gives a +1 formal charge to that atom. Adding extra electron to an atom will give a negative charge to the atom.
(b)
Interpretation: Whether there is any box in the table in model 5 having O atom with 3 bonds and zero lone pairs.
Concept introduction: Losing 1 electron around an atom from its ground state gives a +1 formal charge to that atom. Adding extra electron to an atom will give a negative charge to the atom.
(c)
Interpretation: The reasons for the statement being true should be explained.
Concept introduction: Losing 1 electron around an atom from its ground state gives a +1 formal charge to that atom. Adding extra electron to an atom will give a negative charge to the atom. The occurrence of formal charges can be determined by counting the number of bonds & lone pair.
