2 days ago · Atoms are the basic particles of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms.
3 days ago · Mercury, chemical element, liquid metal of Group 12 of the periodic table. Mercury is the only elemental metal that is liquid at room temperature. Mercury is silvery white and slowly tarnishes in moist air. It alloys with copper, tin, and zinc to form amalgams, or liquid alloys.
5 days ago · Chemical and Physical Properties: The atomic structure contributes to lead’s dense, soft nature, and its low melting point. These properties, combined with its resistance to corrosion, make lead suitable for a wide range of applications.
