Question

part 3 (1 point)
now draw the lewis structure for nh₃o, paying attention to the atom placement you determined in part 2.

Explanation:

Step1: Count valence electrons

N has 5 valence electrons, H has 1 valence electron (3 H atoms contribute 3 electrons), and O has 6 valence electrons. So total valence electrons = 5 + 3+ 6 = 14.

Step2: Determine central atom

Oxygen is likely the central atom as it is more electronegative compared to H and more likely to form multiple bonds. Nitrogen will be bonded to oxygen and hydrogens will be bonded to nitrogen or oxygen.

Step3: Arrange atoms and distribute electrons

Place the O atom in the center. Connect N to O with a single - bond. Place 3 H atoms around N. Distribute the remaining electrons as lone - pairs to satisfy the octet rule. O has 2 lone - pairs and N has 1 lone - pair.

The Lewis structure has O in the center, single - bonded to N. N is single - bonded to 3 H atoms. O has 2 lone - pairs and N has 1 lone - pair.

Answer:

The Lewis structure has O in the center, single - bonded to N which is single - bonded to 3 H atoms. O has 2 lone - pairs and N has 1 lone - pair.
