Boron behaves as :

Options

A. Non-metal
B. Metal
C. Metalloid
D. Transition metal

Answer

To determine how boron behaves, we need to analyze its properties and position in the periodic table. Here’s a step-by-step solution:

### Step 1: Identify Boron's Position in the Periodic Table
Boron is located in Group 13 of the periodic table, which is known as the boron family.

**Hint:** Remember that the periodic table is divided into blocks (s, p, d, f) based on electron configurations.

### Step 2: Determine the Type of Elements in Group 13
Group 13 elements include boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). These elements exhibit varying metallic character, but boron is unique.

**Hint:** Group 13 elements are known for having a mix of metallic and non-metallic characteristics.

### Step 3: Analyze Boron’s Properties
Boron has a small atomic size and a high ionization energy compared to other elements in Group 13. This means it has a lower tendency to lose electrons.

**Hint:** Consider the trends in atomic size and ionization energy as you move down a group in the periodic table.

### Step 4: Compare with Other Groups
Compared to alkali metals (Group 1) and alkaline earth metals (Group 2), boron is much less electropositive. Alkali and alkaline earth metals readily lose electrons, while boron does not.

**Hint:** Electropositivity refers to the tendency of an element to lose electrons and form positive ions.

### Step 5: Conclude Boron’s Behavior
Due to its high ionization energy and low tendency to lose electrons, boron behaves as a non-metal. It is also a poor conductor of electricity, which is characteristic of non-metals.

**Hint:** Remember that non-metals typically have high ionization energies and do not conduct electricity well.

### Final Answer
Boron behaves as a non-metal.
