4. Write the name of metals & non-metals which are found in liquid state.
Answers
Answer:
metals- mercury, gallium, indium,etc
non-metals-helium, bromine, argon, etc
Explanation:
Answer:
☞metals
Liquid metal consists of alloys with very low melting points which form a eutectic that is liquid at room temperature. The standard metal used to be mercury, but gallium-based alloys, which are lower both in their vapor pressure at room temperature and toxicity, are being used as a replacement in various applications.
A few elemental metals are liquid at or near room temperature. The most well known is mercury, which is molten above −38.8 °C (234.3 K, −37.9 °F). Others include caesium, which has a melting point of 28.5 °C (83.3 °F), rubidium (39 °C [102 °F]), francium (estimated at 27 °C [81 °F]), and gallium (30 °C [86 °F]); bromine is also liquid at room temperature (melting at −7.2 °C, 19 °F), but it is a halogen, not a metal.
☞Non-Metals
Non-metals liquid at room temperature - bromine (Br). However, other elements such as caesium (Cs), rubidium (Rb) and francium (Fr) also become liquids at a few degrees above room temperature
