Which block contains metals, non-metals, and metalloids?

📚 Chapter: Classification of Elements and Periodicity in Properties

📘 Detailed Solution

🔵 Step 1: Identify the Blocks

The modern periodic table is divided into four blocks based on the subshell into which the differentiating electron enters:

Block	Groups	General Character
s-block	1–2	Mostly metals
p-block	13–18	Metals, non-metals & metalloids
d-block	3–12	Mostly metals
f-block	Lanthanoids & Actinoids	Metals

🟢 Step 2: The Correct Block

The p-block contains elements showing all three major categories:

⚙️
Metals 🌿
Non-metals 🔶
Metalloids

p-block → Metals + Non-metals + Metalloids

🟣 Examples from the p-Block

Category	Examples
Metals	Al, Ga, In, Sn, Pb, Bi
Non-metals	C, N, O, F, P, S, Cl
Metalloids	B, Si, Ge, As, Sb, Te

Thus, the p-block is unique because it includes elements with a wide range of metallic and non-metallic properties.

🎬 p-Block Property Zone

p-Block (Groups 13–18)

Al
Metal Si
Metalloid P
Non-metal Cl
Non-metal

↓

🎯 All three categories are found in the p-block.

🟠 Important Concept

The p-block extends from Group 13 to Group 18. It contains metals on the left side, metalloids near the zig-zag line, and non-metals mainly towards the right side.

Group 13–18 → p-block

✅ Final Answer

The p-block contains metals, non-metals, and metalloids.

Answer: p-block (Groups 13–18)

Q1. Which block contains metals, non-metals and metalloids?

Solution: The p-block contains metals, non-metals and metalloids. It consists of Groups 13–18.

Q2. Give one example each of a metal, non-metal and metalloid from the p-block.

Solution: Metal – Al; Non-metal – O; Metalloid – Si.

Q1. Explain why the p-block contains different types of elements.

Solution:

1. The p-block contains Groups 13–18.
2. It includes metals, non-metals and metalloids.
3. Metallic character generally decreases from left to right across a period.

p-block → Metals + Metalloids + Non-metals

Q1. Compare the four blocks of the periodic table.

Block	Groups	Main Elements
s-block	1–2	Mostly metals
p-block	13–18	Metals, non-metals & metalloids
d-block	3–12	Transition metals
f-block	Lanthanoids & Actinoids	Inner transition metals

Q1. Describe the position and characteristics of the p-block elements.

Solution:

• The p-block is located on the right side of the periodic table.
• It includes Groups 13–18.
• The differentiating electron enters a p-subshell.
• It contains metals, non-metals and metalloids.
• It includes important families such as halogens and noble gases.

Therefore, the p-block shows the greatest variety of metallic and non-metallic character.

Q1. Explain the classification of elements into s-, p-, d- and f-blocks and identify the block containing metals, non-metals and metalloids.

Solution:

Elements are divided into four blocks according to the subshell into which the differentiating electron enters.

Block	Groups/Series	Characteristic
s-block	1–2	Mostly metals
p-block	13–18	Metals, non-metals & metalloids
d-block	3–12	Transition metals
f-block	Lanthanoids & Actinoids	Inner transition metals

Among these blocks, the p-block has the widest range of properties. Its elements include metals such as Al and Pb, metalloids such as B and Si, and non-metals such as C, N, O and Cl.

🎯 Final Answer:

The p-block (Groups 13–18) contains metals, non-metals and metalloids.
