Question

What metalloids are malleable?

Answer 1

Hint: To solve this question we first need to know what is the property of malleability. The property of a substance to be beaten into foils or thin sheets without cracking or breaking is known as malleability. Most metals are malleable.

Complete answer:
Let us first understand what are metalloids. The chemical elements that show a mixture of properties of metals as well as non-metals are known as metalloids. There are six elements that are commonly recognized as metalloids. These are
1. Boron (atomic number 5)
2. Silicon (atomic number 14)
3. Germanium (atomic number 32)
4. Arsenic (atomic number 33)
5. Antimony (atomic number 51)
6. Tellurium (atomic number 52)
Some fewer classified metalloids are elements
- Carbon (atomic number 6)
- Aluminum (atomic number 13)
- Selenium (atomic number 34)
- Polonium (atomic number 84)
- Astatine (atomic number 85)
All these elements are found in the diagonal region of the p-block in the modern periodic table.
The physical properties of metalloids are
- They exist in solid form.
- They have a lustrous appearance.
- They are brittle.
- They are fair conductors of electricity
- They are semiconductors or exist in semiconducting forms.
From the physical properties of metalloids, we can see that metalloids are brittle, hence none of the metalloids are metalloids.

Note:
The chemical properties of metalloids are
- They behave as a non-metal.
- They have ionization energy between metals and nonmetals.
- They have electronegativity close to 2.
- They form alloys when mixed with metals.
- They form weakly acidic or amphoteric oxides.
