No, Lead Sulfide (galena) is a brittle crystalline solid with semiconducting properties.
PBS metal ore is commonly known as galena. It is the primary ore of lead and has the chemical formula PbS, indicating that it is composed of lead (Pb) and sulfur (S). Galena is characterized by its metallic luster and high density, and it often forms in hydrothermal veins and sedimentary deposits.
The mineral you are referring to is galena. Galena is a dense, metallic mineral that is the primary ore of lead, composed of lead sulfide (PbS). It often appears in a crystalline form and is known for its high density and metallic luster.
PbS is lead (II) sulfide, which contains lead and sulfur.
Only use 1X PBS. 10X PBS is made up because it is easier to store and can be diluted when needed. Labs that use PBS often use it in large quantities so making up 10 or 20 liters at a time is usual and making it up as a concentrate is easier to do.
Galena is a mineral composed primarily of lead sulfide (PbS) and is classified as a metal ore. While it is not a metal itself, it contains the metal lead, which can be extracted from it. In its natural form, galena appears as a dense, metallic-looking mineral, often with a shiny surface.

Metallic bonds are similar to highly delocalised bonds found in giant covalent molecules, such as those found in graphite. Other substances with a metallic appearance such as galena lead sulfide, PbS and iron pyrites, FeS2 although usually considered at high school level to be ionic are in fact semiconductors implying covalency and delocalisation.

PBS YOU was created in 1998.
PBS YOU ended in 2006.
Yes and it was on PBS Kids.
An individual can purchase PBS DVDs directly from the PBS website. PBS stands for Public Broadcasting Services and produces a variety of television shows.
To make 1X PBS from 10X PBS, dilute the 10X PBS solution by mixing 1 part of 10X PBS with 9 parts of distilled water. For example, if you need 100 mL of 1X PBS, combine 10 mL of 10X PBS with 90 mL of distilled water. Mix thoroughly to ensure the solution is homogeneous. Store the diluted 1X PBS at room temperature or refrigerated for future use.
To convert 1x PBS (phosphate-buffered saline) to 10x PBS, you need to dilute the 10x PBS stock solution. Mix one part of the 10x PBS with nine parts of distilled water. For example, to make 1 liter of 1x PBS, combine 100 mL of 10x PBS with 900 mL of distilled water. This dilution will yield the desired 1x concentration.
