Question

_____ is a non-metal present in liquid state.

Answer 1

• Non-metals are those which lack all the metallic attributes.
• They are good insulators of heat and electricity.
• They are mostly gases and sometimes liquid.
• Some of then are even solid at room temperature like Carbon, Sulphur and Phosphorus.
• Under normal conditions of temperature and pressure, some non-metals are found as gases, some found as solids and one is found as liquid. In contrast, except mercury, all metals are solids at room temperature.
• The fact that so many non-metals exist as liquids or gases means that non-metals generally have relatively low melting and boiling points under normal atmospheric conditions.
• In their solid-state, non-metals tend to be brittle.
• Therefore, they lack the malleability and ductility exhibited by metals.
• Ductility is the property of the material to be stretched into wires but non-metals are not ductile except for carbon, as carbon fibres find uses in a wide variety of industries including sports and music equipment.
• Another property characteristic to metals is absent in non-metals called malleability.
• They can’t be drawn into sheets as they are brittle and break on applying pressure.
• Non-metals exhibit very low electrical conductivities.
• The low or non-existent electrical conductivity is the most important property that distinguishes non-metals from metals.
• They are not sonorous and do not produce a deep ringing sound when they are hit with another material.
• They are also bad conductors of heat and electricity except for graphite.

Therefore, Bromine is a non-metal present in liquid state.
