In barium hydride, hydrogen is-

Options

A. Electro positive
B. Electro negative
C. Neutral
D. None of these

Explanation

To determine the nature of hydrogen in barium hydride (BaH₂), we can analyze the properties of the elements involved and their interactions. Here’s a step-by-step solution:

### Step 1: Identify the elements in barium hydride
Barium hydride consists of barium (Ba) and hydrogen (H). Barium is an alkaline earth metal, which is found in Group 2 of the periodic table.

**Hint:** Remember that alkaline earth metals are known for their electropositive nature.

### Step 2: Understand the nature of barium
Barium is highly electropositive. This means it tends to lose electrons easily and form positive ions (Ba²⁺).

**Hint:** Electropositive elements have a tendency to donate electrons.

### Step 3: Understand the nature of hydrogen
Hydrogen can exhibit both electropositive and electronegative characteristics depending on the context. In most compounds, hydrogen behaves as an electronegative element, especially when bonded to metals.

**Hint:** Consider the position of hydrogen in the periodic table and its common bonding behavior.

### Step 4: Analyze the bonding in barium hydride
In barium hydride (BaH₂), barium donates electrons to hydrogen. This means that hydrogen is acting as an electronegative element in this compound because it is accepting electrons from barium.

**Hint:** Look at how elements interact in compounds to determine their roles.

### Step 5: Determine the correct option
Since hydrogen in barium hydride is accepting electrons from barium, it is classified as electronegative in this context. Therefore, the correct answer is that hydrogen in barium hydride is electronegative.

**Hint:** Review the definitions of electropositive and electronegative to confirm your answer.

### Final Answer
In barium hydride, hydrogen is **electronegative**.
