An element X of group 15 exists as diatomic molecule and combines with hydrogen at 773 K in presence of the catalyst to form a compound, ammonia which has a characteristic pungent smell.
Draw the electron dot structure for ammonia and what type of bond is formed in it?

Explanation

To solve the question, we need to follow these steps:

### Step 1: Identify the Element
The element X belongs to Group 15 of the periodic table, which includes nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi). Since the question mentions ammonia (NH₃), we can identify that the element X is nitrogen.

### Step 2: Understand the Formation of Ammonia
Ammonia (NH₃) is formed when nitrogen combines with hydrogen (H) at a high temperature (773 K) in the presence of a catalyst. This reaction can be represented as:
\[ N_2 + 3H_2 \rightarrow 2NH_3 \]
