Step 1:
: Determine the total number of valence electrons in the NH^2− ion.

The nitrogen atom (N) is in the 5th period and group 15 of the periodic table, so it has 5 valence electrons. The hydrogen atoms (H) each have 1 valence electron, and there are two of them. The negative charge on the ion adds one additional electron. Therefore, the total number of valence electrons is: \text{Total valence electrons} = 5 (\text{N}) + 2 (2 \times 1 (\text{H})) + 1 (\text{negative charge}) = 8 \text{ valence electrons}

Step 2:
: Draw the Lewis structure for the NH^2− ion.

Step 3:

Place the nitrogen atom (N) in the center of the structure.

Step 4:

Place the two hydrogen atoms (H) around the nitrogen atom, each sharing one electron with the nitrogen atom.

Step 5:

Place the remaining 4 electrons as lone pairs on the nitrogen atom.

Step 6:

Add a negative charge to the ion. The Lewis structure for NH^2− is: ```lua H : N : H -

Final Answer

Add a negative charge to the ion. The Lewis structure for NH^2− is: ```lua H : N : H -
