When rubbed against a glaze plate, galena (A) leaves a green-black streak. This characteristic streak color helps in identifying the mineral, distinguishing it from others like graphite, hematite, and pyrite, which have different streak colors.
galena, pyrite, and hematite all happen to be distinct in their metallic luster.

The density of galena is between 7,2 and 7,6 g/cm3.
Galena, lead sulfide, is a mineral, not a rock.
Galena is a mineral. not a rock, but is commonly found emplaced in sedimentary rock from hydrothermal deposition in faults and fissures.

galena, pyrite, and hematite all happen to be distinct in their metallic luster.
Galena's streak is gray, hematite's streak is deep maroon/brown.
Hematite is typically a dark gray to black mineral with a reddish streak, while galena is a silvery-gray mineral with a cubic crystal structure. One way to differentiate between them is by performing a streak test: hematite will leave a reddish-brown streak, while galena will leave a gray streak. Additionally, galena is heavier than hematite and has a metallic luster.
Metallic minerals are minerals that have a metallic luster, making them very shiny. A few metallic minerals are Graphite, Galena, Magnetite, and Pyrite. The mineral Hematite can be metallic or nonmetallic

Graphite is a soft, black mineral that leaves a streak on paper and is used in pencils. Galena is a lead-gray mineral that is heavy and often forms cube-shaped crystals. One way to distinguish them is by conducting a streak test - graphite will leave a black streak, while galena will leave a gray streak.

No, we don't use galena is pencils. Galena is the primary ore of the metal lead, and this mineral, PbS, is recovered for that purpose. We also often recover silver as a byproduct of lead processing. It is graphite that is used in pencils, and the mineral graphite is an allotrope of carbon.
No, galena is not the common ore of iron. The common ore of iron is hematite, which is a mineral form of iron(III) oxide (Fe2O3). Galena is actually a mineral form of lead sulfide (PbS).

Pyrite, chalcopyrite, galena, and hematite are common rocks that exhibit metallic lusters. These minerals contain metals such as iron, copper, lead, and sulfur, giving them a shiny, metallic appearance.
