ammonia (nh₃) is

1. has lone pair of electrons
2. bronsted lowry base
3. proton acceptor
4. all of the above

Explanation:

1. Analyze option 1: The Lewis structure of \( \text{NH}_3 \) shows the nitrogen atom has one lone pair of electrons (since N has 5 valence electrons, 3 are used in bonding with H, leaving 1 lone pair).
2. Analyze option 2: A Brønsted - Lowry base is a proton (\( \text{H}^+ \)) acceptor. \( \text{NH}_3 \) can accept a proton to form \( \text{NH}_4^+ \), so it is a Brønsted - Lowry base.
3. Analyze option 3: As a Brønsted - Lowry base, \( \text{NH}_3 \) acts as a proton acceptor (accepts \( \text{H}^+ \) to form \( \text{NH}_4^+ \)).

Since all three statements (1, 2, 3) are true about \( \text{NH}_3 \), the correct option is 4.

Answer:

1. All of the above
