Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air. Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.

Physical properties of matter are characteristics that can be determined without a chemical reaction, such as color, size, weight. Chemical properties are characteristics that can only be determined by a chemical reaction such as irons ability to rust and wood's ability to burn.

1.3: Properties of Matter. All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample).

Lead has 4 valence electrons. Electrons are located around the nucleus of an atom.

like many ionic substances, it could under the right conditions of temperature exist as a vapor consisting of separate molecules of lead iodide, and since it is non linear molecule, Pb (II) iodide has a dipole moment and therefore it would be polar.

Lead is a chemical element with symbol Pb and atomic number 82. Classified as a post-transition metal, Lead is a solid at room temperature.
507052
The same element has different physical properties in different phases or in different compounds. Chemical properties describe a substance's ability to react and form new substances. They can only be tested by reacting the material with other things to see how it changes.

Therefore, thermal decomposition of lead dioxide is a common way of producing various lead oxides. Lead dioxide is an amphoteric compound with prevalent acidic properties. It dissolves in strong bases to form the hydroxyplumbate ion, [Pb(OH)6]2−: PbO2 + 2 NaOH + 2 H2O → Na2[Pb(OH)6]

These include: color, streak, hardness, luster, diaphaneity, specific gravity, cleavage, fracture, magnetism, solubility, and many more. These physical properties are useful for identifying minerals. However, they are much more important in determining the potential industrial uses of the mineral.

Physical properties Antimony is a silvery-white, shiny element that looks like a metal. It has a scaly surface and is hard and brittle like a non-metal. It can also be prepared as a black powder with a shiny brilliance to it. The melting point of antimony is 630°C (1,170°F) and its boiling point is 1,635°C (2,980°F).
