Question

Arsenic element is:

• A. Metal
• B. Non-metal
• C. Metalloid
• D. Inert

Hint:

Metalloids have both metallic and non-metallic properties. Examples include arsenic, silicon, and boron.

Answer 1

The Correct Option is C

Arsenic is classified as a
metalloid, which means it exhibits properties that are intermediate between those of metals and non-metals. This unique classification arises because metalloids possess a mix of metallic and non-metallic characteristics. \smallskip 1.
Properties of Metalloids:

Metalloids like arsenic can conduct electricity better than non-metals but not as well as metals, which is why many of them behave as
semiconductors.
They may be brittle like non-metals but can have a metallic luster or appearance.
Chemically, metalloids can exhibit behavior typical of both metals and non-metals depending on the reaction conditions.
\smallskip 2.
Position in the Periodic Table:

Metalloids are typically found along the "stair-step" line or zig-zag boundary on the periodic table that separates metals on the left and non-metals on the right.
Arsenic is located near this boundary, which explains its intermediate properties.
\smallskip 3.
Significance:

The semiconductor behavior of arsenic and other metalloids makes them valuable in electronic devices and industry.
Understanding arsenic’s metalloid nature helps in predicting its chemical reactivity and physical characteristics.
\smallskip In summary, arsenic’s classification as a metalloid reflects its intermediate physical and chemical properties, placing it between metals and non-metals both in behavior and position on the periodic table.
