  • Arsenic (As): Properties, Uses and Periodic Table Guide

    Periodic Table Guide

    Arsenic (As) has atomic number 33 and is classified as a metalloid. It sits in Group 15, period 4 of the periodic table. Its practical relevance includes compound semiconductors, specialty alloys and limited industrial chemical applications under strict controls.

    Quick facts

    Atomic number 33 Symbol As
    Relative atomic mass 74.9216 State at room temperature Solid
    Group 15 Period 4
    Classification metalloid Block p-block

    Position in the periodic table

    Metalloids sit near the boundary between metals and nonmetals. Their intermediate electrical and chemical behavior makes several of them especially important in semiconductors, glass, ceramics and electronic materials.

    Arsenic belongs to period 4. Its position helps explain recurring trends such as atomic size, bonding behavior, oxidation states and the way it interacts with neighboring elements.

    Why Arsenic matters

    In engineering and technology, arsenic is associated with compound semiconductors, specialty alloys and limited industrial chemical applications under strict controls. The importance of the element may come from the pure element itself, from compounds containing it, or from its role as an alloying, electronic, catalytic or nuclear material.

    Engineering and scientific context

    Material behavior should never be inferred from the element name alone. Purity, isotope composition, crystal structure, processing history, temperature and the surrounding chemical environment can all change performance. In alloys and compounds, the contribution of arsenic depends on concentration and interaction with the other constituents.

    Safety and handling

    Arsenic and several of its compounds can present significant toxicological hazards. Exposure limits, waste controls and the exact chemical form must be considered before industrial use.
